Low-voltage equipment is designed for handling low voltages at consumer-level. This includes computing and telecommunications systems, power distribution grids and PV systems, and EV charging facilities. Exposure to sudden high voltage surges, for example, from switching or lightning, can damage or destroy low-voltage equipment. Protection of low-voltage equipment and systems from such phenomena is thus vital for human safety as well as preventing damages, and so understanding the processes and protective countermeasures is of great importance. This book offers a systematic and thorough treatise of the topic for researchers in industry and universities as well as utility experts and advanced students and more generally for all people involved in electromagnetic compatibility or designing surge protection systems and lightning protection systems. The book aims to provide answers to all readers' questions from the simplest to the most complicated, including guidance on the application of surge protective devices (SPD) illustrated by many cases studies. Following an introduction, chapters cover lightning and surges, risk assessment, standard environment, surge protection (surge protective components and surge protective devices), and their applications, new trends and unsolved challenges.

With the integration of more distributed or aggregated renewables, and the wide utilization of power electronic devices, modern power systems are facing new stability and security challenges, such as the weakly damped oscillation caused by wind farms connected through long distance transmission lines, the frequency stability problem induced by the reduction of inertia and the voltage stability issue resulting from the interactions between transmission systems and dynamic loads. Meanwhile, synchronized phasor measurement technology developed very fast in the last decade, and more phasor measurement units (PMUs) and wide area measurement systems (WAMSs) have been deployed. These provide more insights into the system dynamics and approaches to overcoming the new challenges. This book addresses the emerging concepts, methodologies and applications of wide area monitoring, control and protection in power systems with integrated large scale renewables. Chapters cover monitoring, modelling and validation, control, and data mining with an emphasis on synchrophasor technology, and experiences with real power grids.

Containing papers from the 3rd International Conference on Energy Production and Management: The Quest for Sustainable Energy, this book discusses the future creation and use of energy resources. It also examines the issue of converting new sustainable sources of energy into useful forms, while finding efficient methods of storage and distribution. An important objective of the book is discussing ways in which more efficient use can be made of conventional as well as new energy sources. This relates to savings in energy consumption, reduction of energy losses, as well as the implementation of smart devices and the design of intelligent distribution networks. This volume provides a comparison of conventional energy sources, particularly hydrocarbons, with a number of other ways of producing energy, emphasising new technological developments, based on renewable resources such as solar, hydro, wind and geothermal. In many cases the challenges lie as much with production of such renewable energy at an acceptable cost, including damage to the environment, as with integration of those resources into the existing infrastructure. The changes required to progress from an economy based mainly on hydrocarbons to one taking advantage of sustainable energy resources are massive and require considerable scientific research as well as the development of advanced engineering systems. Such progress demands close collaboration between different disciplines in order to arrive at optimum solutions.

The application areas of batteries are currently booming. The recent generation of devices combines a high energy density with a reasonable cost and life expectancy, making them suitable not only for cars but also electric bikes, scooters, forklifts, gardening and household tools, storage batteries as well as airborne applications such as drones, helicopters, and small airplanes. Since manufacturing batteries requires a lot of energy and minerals, extending the life of the battery is worthwhile from both an ecologic and an economic point of view. The use of Battery Management Systems (BMS) can extend battery life, if they are used with a sound understanding of the internal electrical processes. This book provides insight into the electric behaviour of batteries for researchers involved with the design of battery management systems, and experts involved with electric vehicle development. It covers a range of options for designing battery management and cell balancing systems, with a focus on inductive balancing. After an overview of previous and current battery types, chapters convey a number of cell-balancing techniques, such as passive and active equalizer circuits, with a focus on transformer and coupled inductor based balancing methods. In addition, cell voltage monitoring and charging are investigated. Furthermore, solutions are provided to reduce the number of inductive components, the number of windings, and practical implementation.

Power systems are becoming increasingly complex, handling rising shares of distributed intermittent renewable generation, EV charging stations, and storage. To ensure power availability and quality, the grid needs to be monitored as a whole, by wide area monitoring (WAM), not just in small sections separately. Parameter oscillations need to be detected and acted upon. This requires sensors, data assimilation and visualization, comparison with models, modelling, and system architectures for different grid types. This hands-on reference for researchers in power systems, professionals at grid operators and grid equipment manufacturers, as well as for advanced students, offers a comprehensive treatment of advanced data-driven signal processing techniques for the analysis and characterization of system data and transient oscillations in power grids. Algorithms and examples help readers understand the material. Challenges involved in realistic monitoring, visualization, and analysis of actual disturbance events are emphasized. Chapters in this second edition cover WAM and analysis systems, WAM system architectures, modelling of power system dynamic processes, data processing and feature extraction, multi-sensor multitemporal data fusion, WAM of power systems with high penetration of distributed generation, distributed wide-area oscillation monitoring, near real-time analysis and monitoring, and interpretation and visualization of wide-area PMU measurements.

Wind energy is often framed as a factor in rural economic development, an element of the emerging "green economy" destined to upset the dominant greenhouse- gas-emitting energy industry and deliver conscious capitalism to host communities. The bulk of wind energy firms, however, are subsidiaries of the same fossil fuel companies that wrought havoc in shale-gas and coal-mining towns from rural Appalachia to the Great Plains. On its own, wind energy development does not automatically translate into community development. In Governing the Wind Energy Commons, Keith Taylor asks whether revenue generated by wind power can be put to community well-being rather than corporate profit. He looks to the promising example of rural electric cooperatives, owned and governed by the 42 million Americans they serve, which generate $40 billion in annual revenue. Through case studies of a North Dakota wind energy cooperative and an investor-owned wind farm in Illinois, Taylor examines how regulatory and social forces are shaping this emerging energy sector. He draws on interviews with local residents to assess strategies for tipping the balance of power away from absentee-owned utilities.

Energy and power are fundamental concepts in electromagnetism and circuit theory, as well as in optics, signal processing, power engineering, electrical machines, and power electronics. However, in crossing the disciplinary borders, we encounter understanding difficulties due to (1) the many possible mathematical representations of the same physical objects, and (2) the many possible physical interpretations of the same mathematical entities. The monograph proposes a quantum and a relativistic approach to electromagnetic power theory that is based on recent advances in physics and mathematics. The book takes a fresh look at old debates related to the significance of the Poynting theorem and the interpretation of reactive power. Reformulated in the mathematical language of geometric algebra, the new expression of electromagnetic power reflects the laws of conservation of energy-momentum in fields and circuits. The monograph offers a mathematically consistent and a physically coherent interpretation of the power concept and of the mechanism of power transmission at the subatomic (mesoscopic) level. The monograph proves (paraphrasing Heaviside) that there is no finality in the development of a vibrant discipline: power theory.
