Nanogrids are small energy grids, powered by various generators often including photovoltaics. For example, a nanogrid might supply a village in a rural area and allow that village to trade its surplus energy. A picogrid is a still smaller energy grid. IRENA defines nanogrids as systems handling up to 5 kW of power while picogrids handle up to 1 kW.

Nanogrids and picogrids can play roles in urban, suburban and rural areas, particularly in developing countries, and can help with decarbonising the energy systems and empowering citizens. Electric vehicles (EV) are poised to play...

Thermal management is an issue with all electrical machines, including electric vehicle drives and wind turbine generators. Excessively high temperatures lead to loss of performance, degradation and deformation of components, and ultimately loss of the system.

Cooling of Rotating Electrical Machines: Fundamentals, modelling, testing and design provides a foundation of heat transfer and ventilation for the design of machines. It offers a range of practical approaches to the thermal design, as well as design data and case studies. Chapters cover fundamentals of heat transfer,...

Fuses are designed to operate when over-currents, large and small, occur within electrical equipment; they thus interrupt the flow of current, preventing damage. They are needed for various power electric systems, for stationary and automotive applications, as well as power grid components like PV systems and distribution lines. Different types of equipment and voltages require special fuses, and their behaviour must be understood to guarantee correct choice and safe operation.

For the 3rd edition in 2004, Wright and Newbery's classic had been revised to include pre-arcing and arcing...

Demand response (DR) describes controlled changes in the power consumption of an electric load to better match the power demand with the supply. This helps with increasing the share of intermittent renewables like solar and wind, thus ensuring use of the generated clean power and reducing the need for storage capacity.

This book conveys the principles, implementation and applications of demand response. Chapters cover an overview of industrial DR strategies, cybersecurity, DR of industrial customers, price-based demand response, EV, transactive energy, DR with residential appliances,...

Nuclear energy is contributing to the long-term solution to stave off climate change. However, current nuclear fission technology accesses only about 1-3% of the nuclear energy content of natural uranium, which is inefficient, and also creates a radioactive waste disposal problem.

Combining nuclear fission technology with emerging nuclear fusion technology to create a fusion-fission hybrid would yield extra fusion neutrons to 1) convert much more of the uranium into fissionable material, which would increase efficient utilization of the nuclear fuel resource, and 2) significantly...

State estimation is a key function for real-time operation and control of electrical power systems since its role is to provide a complete, coherent, and reliable network real-time model used to set up other real-time operation and control functions. In recent years it has extended its applications to monitoring active distribution networks with distributed energy resources. The inputs of a conventional state estimator are a redundant collection of real-time measurement, load and production forecasts and a mathematical model that relates these measurements to the complex nodal voltages,...

Smart grids with distributed clean energy generation, storage and prosumers are the future of energy systems. They need two-way digital communication between multiple customers and suppliers of energy, to produce, buy and sell electricity to the grid at small scales. These arrangements need a system that maintains, checks, and registers information about transactions.

Blockchain technology is able to handle these requirements with smart contracts, peer-to-peer energy trading and immutable transactions. A blockchain is a digital ledger of transactions that can be accessed across the...

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...

Power systems are becoming increasingly complex as well as flexible, able to integrate distributed renewable generation, EV, and additional loads. This expanded and updated second edition covers the technologies needed to operate modern power grids.

Initial chapters cover power system modelling, telegrapher equations, power flow analysis, discrete Fourier transformation and stochastic differential equations. Ensuing chapters deal with power system operation and control, power flow, real-time control and state estimation techniques for distribution systems as well as shipboard...

Microgrids use ICT to intelligently deliver energy and integrate clean generation. They can operate independently from a larger grid and can help to strengthen grid resilience. Applications include remote as well as urban areas, hospitals, and manufacturing complexes. Cybersecurity challenges arise, exposing the microgrids to cyber-attacks, possibly resulting in harm to infrastructure and to people. Research has classified attacks based on confidentiality, integrity, and availability, and most countermeasures focus on specific attacks or on protecting specific components. A global approach...
