Overview: This article explores the opportunities and challenges of integrating clean technologies and information and communication technologies for efficient and sustainable energy management in smart grids.  Decarbonization has accelerated the fundamental shift in society toward clean technologies. Electrical energy will be a significant factor in the decarbonization process. Electrical energy is one of the most common forms of energy carriers and is seeing growing usage. Increasing electricity demand forces the expansion of the generation and transmission systems, requiring a significant amount of investment.  Power loss and reactive power flow in the transmission systems make the conventional, centralized structure of power systems less efficient. Distributed generations (DGs) have been incorporated into low- and medium-voltage distribution networks in order to increase system availability, efficiency, and cost-effectiveness. Furthermore, renewable-based distributed generation aids in the decarbonization of the electric energy sector.Evolution of Smart GridDistribution systems that have been powered up can function as a microgrid in the absence of the utility grid. A microgrid is an island-based distribution system that uses local distributed generation and energy storage to provide critical loads in island mode. Distribution systems with microgrid capabilities will have some benefits, such as increased productivity, dependability, accessibility, and power quality.  However, information and communication technologies (ICTs) are necessary for the optimal and reliable operation of various distributed generation and energy storage systems in microgrids. To operate modern energy distribution systems as efficiently and dependably as possible, the smart grid concept has been introduced. To operate and plan grid systems with irregular output and variable power sources, ICTs must be available at both the generation and transmission levels. These systems enable power systems to meet customer demands by intelligently monitoring, making decisions, and controlling contemporary power systems. In addition to incorporating DGs into distribution networks, large-scale renewable power plants like photovoltaic (PV) and wind energy systems have been widely installed in power systems, and the power grids are currently moving toward more fully renewable energy systems. Figure 1. Concept of a Distributed Power Generation System Source IEEE Access Along with efficiency, flexibility, and operability benefits, smart grid technologies also present new difficulties for the design and management of modern power systems. Restructuring the power grids to incorporate renewable energy sources, microgrid technologies, ICTs, and power electronics can result in these difficulties. Smart Grid’s Future DirectionsThe idea of smart grids has changed with the development of technology. In recent years, the smart grid's research and development have increased. As a result, the implementation of smart grids has changed from virtual to real-time. However, there are several situations in which action needs to be taken to turn it into a complete real-time network service.Big Data ManagementThe input of real-time data is a key factor in a smart grid. It serves as the backbone of the network's functioning. Power transmission, generation, transformation, and utilization data are being collected for reliable and efficient working. All decisions are made based on the information gathered. The collection and management of such a vast amount of real-time data is a significant problem.  To predict the demand for energy at various locations, the algorithms must use all the data gathered from the sensors and associated devices. To produce the best results, the algorithms must be optimized. One of the main study subjects in smart grid technology is IT infrastructure, data gathering, governance, data processing, and, most critically, data security.Investing in Smart Grid InfrastructureTo reduce carbon emissions, a number of countries have started implementing smart grid infrastructure. Many of them are engaged in projects designed to evaluate the feasibility of the network. The construction of the smart grid infrastructure has already started in nations including Australia, South Korea, and Japan. The initial investment, though, is the main concern. The ongoing maintenance of the entire network further raises the overall cost.  Therefore, before making an investment of this size in the infrastructure, a thorough financial report should be made. The price of smart grids in a few emerging nations is shown in Table 1. This will estimate the starting sum that a developing nation must invest in order to create smart grid infrastructure. Additionally, it will provide a general concept of the maintenance costs as well as any other extra expenses necessary to guarantee the network's efficient operation.Business Model RestructuringThe business model has undergone considerable adjustment as a result of the new smart grid's emergence. New technologies have altered consumer perceptions and created a network of distributed power sources. Consequently, business practices are evolving. It is necessary to implement new policies to benefit consumer communications. To integrate the load and the generated power, the utility business model should be put into practice at the distribution level.Modernization of the Energy Production SystemCustomer needs have evolved due to the smart grid's evolution. As a result, there are fluctuations in energy demand. To accommodate the demand response, the system's capacity should be raised. Additionally, the energy-producing systems must change their production policies to integrate into the smart grid network. In the smart grid network, cloud-based data management strategies are applied. The existing system needs to be upgraded and changed in order to establish IoE activities.  Cyber-physical power systems are the smart operation of future power systems, which include distributed generation, microgrids, and demand side management while utilizing information and communication technologies over the physical system. The ICTs are vulnerable to cyberattacks, data loss, and hardware failure. ICT malfunctions will reduce system performance and must be taken into account when planning a power system. Additionally, when operating power systems, cybersecurity must be taken into consideration because malicious intrusions from cyberattacks could result in a loss of power or energy. The network should incorporate security measures against cyberattacks.Summarizing the Key PointsThe paper highlights the importance of information and communication technologies in the optimal and reliable operation of distributed generation and energy storage systems in microgrids.The integration of information and communication technologies with power systems can lead to the development of cyber-physical power systems or smart grids.Smart grids enable power systems to meet customer demands by intelligently monitoring, making decisions, and controlling contemporary power systems.However, the adoption of clean technologies and information and communication technologies presents new challenges for the design and management of modern power systems.Smart grid technologies also present new difficulties for design and management but offer significant benefits such as flexibility, efficiency, operability, reliability, accessibility, and power quality. Reference(s)1.Peyghami, S., Palensky, P., & Blaabjerg, F.

Brushless motors generate rotational force by synchronizing the energization of multiple windings through electronic commutation. They are lightweight, compact, and provide precise control over motor speed and torque, making them ideal for drone applications.Fig 2: Brushless Motors4. Multi-Rotor control board: In this study, the drone has controlled via a Multi-Rotor control board. The multi-rotor's flying is managed by this controller. Its purpose is to stabilise the aircraft during flight and to do this, it takes signals from on-board gyroscopes (roll, pitch and yaw) and passes these signals to the Atmega324PA processor, which processes signals according the users designated firmware and passes the control signals to the mounted ESCs (Electronic Speed Controllers) and the mixture of these signals commands the ESCs to make fine adjustments to the motors rotational speeds which stabilises the craft. The Multi-Rotor control board additionally utilises radio signals via a receiver and transmits these signals, together with stabilisation signals, to the Atmega324PA IC via the user demand inputs for the aileron, elevator, throttle, and rudder. This information is analysed and delivered to the ESCs. It controls each motor's rotational speed to regulate the direction of flight (up, down, backwards, forwards, left, right, and yaw).Fig 2: Multi-Rotor control board5. Batteries and Power Distribution:Drones require a reliable power source to operate. Lithium-polymer (LiPo) batteries are commonly used due to their high energy density and lightweight characteristics.

Wireless communication technologies such as Wi-Fi, Bluetooth, or radio frequency (RF) systems are commonly used. These systems ensure reliable and secure communication, enabling remote control, real-time video streaming, and swarm coordination in the case of multiple drones operating together.10. Safety and Redundancy Systems:To enhance safety and reliability, drones may incorporate various electronic components and systems. These can include redundant power systems, redundant flight controllers, backup sensors, and fail-safe mechanisms. Redundancy helps mitigate the risk of component failures and ensures that critical functions can continue operating in case of a system fault, improving the overall safety and resilience of the drone. 11. Transmitter and Receiver:The transmitter and receiver form the radio control system of a drone, enabling remote control and communication between the pilot and the drone. The transmitter is the handheld device held by the pilot, while the receiver is installed on the drone itself.Key aspects of the transmitter and receiver electronics components include:Transmitter: The transmitter is the control interface held by the pilot. It consists of control sticks, switches, buttons, and other input mechanisms. These controls allow the pilot to send commands and inputs to the drone, such as adjusting throttle, controlling direction, changing flight modes, or activating specific features. The transmitter typically operates on specific frequency bands and employs various modulation techniques to ensure reliable communication with the receiver.Receiver: The receiver is the counterpart of the transmitter installed on the drone. It receives the commands sent by the pilot through the transmitter and decodes them into control signals that are understood by the drone's flight controller. The receiver is connected to the flight controller or autopilot system, allowing the drone to interpret and execute the pilot's commands accurately.Antennas: Both the transmitter and receiver have antennas for transmitting and receiving radio signals. These antennas ensure the effective transmission and reception of control signals between the pilot and the drone. They can be external or internal, depending on the design of the drone and the radio system used. 12. Landing Gear:Landing gear provides support and protection for the drone during takeoff, landing, and ground operations. The design of the landing gear may vary depending on the drone's purpose, size, and terrain it operates in. Key aspects of drone landing gear include:Legs: The landing gear consists of legs that are attached to the drone's frame.

Overview: This article explores how the smart grid, with its IoT-based transactions, can help address energy challenges in the 21st century. Learn about the role of renewable power generation and electrical grid infrastructure in energy conservation.  "Smart Grid" (SG) refers to the upgraded electrical grid that was made possible by advances in communication and sensor technology. Developing smart grid infrastructure is one of the solutions to many problems regarding energy conservation.Challenges in Energy TransactionsThere is an increase in the amount of energy produced by solar and wind sources. Additionally, there are new loads, such as electric vehicles, heat pumps, smart residential cities, commercial and industrial usage, infrastructure, substations, etc. Due to these characteristics, additional technological challenges, notably the unpredictability of solar, wind, and electric vehicle charging stations, represent a significant challenge in the process of distributing energy, which is a critical issue.  Energy demand has been rising rapidly due to the expansion of industries and population density. To prevent an energy crisis in the future, attention is being paid to energy consumption. Due to a lack of dependability, efficiency, security, seamless connectivity, etc., conventional electrical energy and networks would not be able to meet the needs of the industry in the 21st century. As a result, many new technologies (including communication and sensors) have developed to offer the features listed above.Evolution of Internet of EnergyThe Internet of Things (IoT) has evolved due to the expansion of heterogeneous networks and smart devices, enabling all networks and devices to interact with one another and create communication links with one another. The Internet of Things will be very helpful in the smart grid because it manages numerous components and seeks to give users the best possible energy.  The Internet of Things (IoT) is becoming more popular in smart grids under the "Internet of Energy" (IoE). To deliver the best energy and share relevant data among the numerous entities connected to the grid, smart grid technology uses all newly developed communication technologies and creates a completely connected network. A major problem has been the administration of enormous amounts of real-time data and its integration.  In contrast to the Internet of Things, the Internet of Energy is one of the most recent approaches to addressing issues like uninterruptible services, optimal use, etc. This article describes how the smart grid will use the Internet of Things to manage energy effectively. This also discusses how communication technologies integrate various smart grid components, infrastructure entities, substations, electric vehicles, etc. Advantages of Internet of Energy-based Smart GridsThe Internet of Energy enables optimal power distribution to all grid-connected devices and information sharing inside the grid network. Energy management, electric vehicle integration, and network integration will all be crucial in smart grids. Vehicle-to-grid (V2G) and grid-to-vehicle (G2V) technology have established a road to deal with the integration. With this technology, automobiles can communicate data with infrastructure about their state of charge (SOC), battery life, and condition, in addition to receiving the best possible energy supply. Due to the rapidly expanding energy consciousness, a dependable system that can deliver high-quality energy with optimal output and a sustainable backup system is required. This is why the smart grid is so unique because of the way it became linked to the bidirectional network system. The multi-agent system (MAS) will be employed in industries to manage the smart grid without human interaction. The software component known as the multi-agent system is responsible for gathering and delivering necessary data throughout the network. Challenges in SecurityThe effective formation of communication between entities aids in the handling of the massive amount of real-time data using reliable, secure encryption techniques. Only permitted entities should be able to manage network data exchange. Data management and security will become important challenges while dealing with a large volume of data and powering every device connected to the grid. The grid network will be more vulnerable to cyberattacks, which might cause individual components and the network as a whole to malfunction.  It results in the flow of incorrect information between entities and end users. Therefore, it is necessary to give the grid high security. Strong protocols (including encryption and decryption), anti-malware software, and highly secure network management protocols are required for high security.Features of Internet of EnergyThe smart energy infrastructure shown in Fig. 1 is a networked system comprising loads, energy metering units, energy storage devices, and automated and centralized distribution systems. Power and energy distribution across the network is the Internet of Energy’s primary goal, and it also enables information sharing with all linked devices. It deals with the security and management of real-time data. Cloud and edge-based systems are fully necessary for implementing the "Internet of Energy" concept.  Open-source interfaces are necessary for creating customer-specific applications to make the Internet of Energy quick and effective. The cloud-based application system at the power grid substation compares the actual target with the current target demand. It offers services like security management and power delivery to remote locations. The substation-connected assets were tracked, examined, and shared using the Internet of Energy.  Once the data analysis process is complete, the appropriate entity will permit the necessary steps, transforming the power plant and smart grid from a traditional into a virtual system. The advanced distributed energy management system's use of technology improves the effectiveness of power usage. Utilizing appropriate optimization techniques at various levels maximizes output while lowering costs, boosting profitability, improving dependability, and incorporating more renewable resources into the smart grid network.  The administration of smart meters, grid analytics, sub-station devices, low voltage outage management systems, and distributed energy resource management systems are some advanced applications integrated with the Internet of Energy.

Electrical engineering and electronics traverse many fields of technological innovations and are in the foreground for groundbreaking advancements. Over the years, electrical and computer engineering have pioneered and contributed to developing more streamlined design, development, testing and improved manufacturing processes for frontier-end electronics, devices and equipment. In the strive for streamlining and in pursuit of innovation, the electrical and electronics industry has rapidly edged into the ever-expanding applications of artificial intelligence and machine learning.With the emergence of new technologies such as IoT, artificial intelligence (AI), machine learning (ML) and deep learning, the electronics and electrical industry is adopting and embracing major changes that lead to faster workflows, through optimization, automation and removing redundancies. ML and AI in industrial setups are designed to optimize systems and improve efficiency. This is possible as these systems are equipped with sensors and analytical processes that compute and interpret the data providing useful information.For instance, engineers create networks of interconnected cameras and sensors to guarantee that an autonomous vehicle's AI can "see" its surroundings. They must also make sure that the data is transmitted from these onboard sensors as quickly as possible because any lag in processing might cause a serious mishap.The electrical and electronic industry has seen significant advancements in recent years, with the emergence of artificial intelligence (AI) and machine learning (ML) revolutionizing the way we design, build, and operate electrical systems and devices. AI and ML technologies are increasingly being used to optimize performance, reduce costs, and improve efficiency across a range of applications in the industry. From predictive maintenance and fault detection to energy management and personalization, AI and ML are transforming the electrical and electronic industry in unprecedented ways. This article provides an overview of the role of AI and ML in the industry, examining their applications, benefits, and prospects.To start with let us understand what the terms AI and ML mean and how they are different.What are AI and ML?Artificial intelligence (AI) and Machine learning are often used synonymously although there are some differences between these two terms. To understand AI, it is important to first define what is machine learning and differentiate it from artificial intelligence.Artificial Intelligence is commonly known as AI, which refers to the development of computer systems, embedded systems and logical processing that can perform tasks that typically require human intelligence, such as learning, problem-solving, decision-making, and language processing.  For computer systems to learn and mimic human intelligence, they need to learn from a large dataset. For computers to learn from data, adapt to changing settings, and carry out activities that would otherwise require human involvement, artificial intelligence (AI) entails the creation of algorithms, machine learning models, and other approaches. Self-driving cars, voice recognition, image and speech recognition, fraud detection, and many more uses for AI are becoming more prevalent.Machine Learning or ML for short is a basic subset of AI. Basically, it involves the design and development of simple or complex algorithms and models that enable computers to learn from data, make analyses and improve their performance on a task without being explicitly programmed. Machine learning algorithms can learn from a large dataset to identify patterns, correlations and relationships, and then use that knowledge to make predictions or decisions on predictive new data. Machine learning can thus be described as a way of predicting the future based on presented parameters. There are three main types of machine learning: supervised learning, unsupervised learning, and reinforcement learning. ML is used in a wide range of applications, including image and speech recognition, natural language processing, recommendation systems, and predictive maintenance, among others.Artificial Intelligence and Machine Learning in the Electrical and Electronics IndustryThe term artificial intelligence as used in the electrical and electronics industry generally refers to a variety of systems and technologies built to imitate human intelligence by making decisions and solving related problems. In recent years, engineers and scientists have explored different applications and ways in which AI can be applied in electrical systems.Some of the most common ways in which AI is incorporated into electrical systems and consumer electronics:• Expert systems: Expert systems are a subset of artificial intelligence (AI) systems that employ an inference engine to derive conclusions from a knowledge base containing data on a particular area. If-then rules that are drawn from the knowledge of human subject-matter experts often make up the knowledge base. To offer a solution or suggestion, the inference engine applies these principles to the data or issue at hand. Since the 1970s, expert systems have been utilized for a variety of tasks, including financial planning, technical problem-solving, and medical diagnosis. They have the potential to successfully automate decision-making procedures and lessen the requirement for human expertise in specific jobs. They may not always deliver correct or timely information due to their limits in dealing with complicated or dynamic circumstances.• Fuzzy logic control: Fuzzy logic is a mathematical framework that deals with uncertainty and imprecision, and fuzzy logic control systems employ fuzzy logic to make choices and manage operations. Traditional control systems base judgments on exact numerical values, whereas fuzzy logic control systems base decisions on the degree to which linguistic variables are members of fuzzy sets. In complicated control systems, where it may be challenging to set precise numerical values for every input variable, fuzzy logic control systems are particularly helpful in cases when there is ambiguity or imprecision in the data.• Machine Learning: The creation of algorithms and models for machine learning (ML) enables computers to learn from data and enhance their performance on a job without being explicitly programmed. A huge dataset may be used by machine learning algorithms to detect patterns and correlations, which can subsequently be applied to fresh data to produce predictions or choices.• Artificial Neural Networks: A class of machine learning model known as artificial neural networks (ANNs) is modelled after the structure and operation of biological neural networks in the human brain. Artificial neurons, also known as neurons, are linked nodes that are arranged in layers to form ANNs. Each neuron in the network takes input signals from neighbouring neurons or outside sources, analyzes them using an activation function, and then generates an output signal that is sent to other neurons.• Deep Learning: To train artificial neural networks with many layers and enable them to learn hierarchical representations of the input data, deep learning is a subset of machine learning. Deep learning models are highly suited for a variety of applications, including image and audio recognition, natural language processing, and autonomous systems since they can automatically learn to discover complex patterns and correlations in the data. To alter the weights of the connections between the neurons in the network, deep learning models are often trained using a large dataset and an optimization technique, such as stochastic gradient descent.Application of AI and ML in the Electrical and Electronics IndustryThe design, construction, and use of electrical systems and devices are being transformed by artificial intelligence (AI) and machine learning (ML), which are becoming more and more relevant in the electrical and electronic industries. The industry is being impacted by AI and ML in the following ways:• Predictive maintenance: AI and ML algorithms may be used to identify when electrical equipment is most likely to fail and plan repair, cutting down on both maintenance costs and downtime.• Optimization: AI and ML models can be used to analyze large sets of data and make the decision based on the data. Machine learning algorithms can be used to optimize the performance of electrical systems and devices, ensuring that they are operating at peak efficiency. This optimizes processes, equipment and devices to perform more efficiently.• Fault detection and diagnosis: AI and ML algorithms can be used to detect and diagnose faults in electrical systems, allowing for more accurate and efficient troubleshooting and repair. The process can be based on the information collected by the sensor in systems or by predictive analysis based on previous parameters.• Energy management: Energy management is one of the most vastly used applications of AI due to its ability to compute and make a logical decision in homes and industrial setups. AI and ML can be used to optimize energy consumption in buildings and homes, reducing energy waste and saving money on energy bills.• Design optimization: AI and ML algorithms can be used to optimize the design of electrical systems and devices, improving performance and reducing costs.• Robotics and Automated Assembly: By automating the assembly of electrical components, AI and ML can increase productivity and decrease the need for manual labour. Algorithms can quickly and accurately detect and manipulate electrical components using computer vision and other approaches AI and ML are critical for developing and improving the performance of robots and automated systems used in manufacturing and other industries.• Personalization: Smart bulbs, smart homes and smart devices are based on the idea of customizing and personalizing technology. AI and ML can be used to create personalized electrical devices that adapt to individual user preferences, improving the user experience. These devices operate depending on the preferences of an individual or a particular setting thus making them customizable. • Smart Grid Management: The electricity grid can be managed more effectively with the help of AI and ML. Algorithms can find possibilities to decrease energy waste and suggest modifications to optimize the distribution of electricity by evaluating data on energy consumption trends.• Quality Control: Quality control in the traditional manufacturing process and assembly is a manual process that is often inaccurate and done through sampling. Throughout the manufacturing process, electrical component flaws may be automatically detected using AI and ML. Algorithms may find flaws and eliminate problematic parts by evaluating photos and other data, therefore raising the calibre of the final output.Overall, artificial intelligence (AI) and machine learning (ML) are revolutionizing the electrical and electronic sectors, allowing engineers to create, construct, and use electrical systems and gadgets more successfully and efficiently than ever before.FAQs1.What is the difference between AI and machine learning? AI refers to the broader field of creating intelligent machines that can perform tasks that typically require human intelligence, while machine learning is a subset of AI that involves training algorithms to make predictions or decisions based on data.2.How are AI and ML used in the electrical and electronics industry? AI and ML are used in a wide range of applications in the electrical and electronics industry, including predictive maintenance, process optimization, fault detection and diagnosis, energy management, and smart grid management.3.What are the benefits of using AI and ML in the electrical and electronics industry?The benefits of using AI and ML in the electrical and electronics industry include improved efficiency, increased productivity, reduced downtime, improved safety, and cost savings.4.What are the challenges of implementing AI and ML in the electrical and electronics industry? The challenges of implementing AI and ML in the electrical and electronics industry include the need for large amounts of high-quality data, the complexity of developing and training models, the cost of implementing new technologies, and the need for specialized skills and expertise.5.What are some popular AI and ML techniques used in the electrical and electronics industry? Some popular AI and ML techniques used in the electrical and electronics industry include artificial neural networks, fuzzy logic control systems, deep learning, reinforcement learning, and genetic algorithms.6.What are some examples of AI and ML applications in the electrical and electronics industry? Some examples of AI and ML applications in the electrical and electronics industry include energy demand forecasting, predictive maintenance of electrical equipment, automated fault detection and diagnosis, and optimization of power grids.
