During the rapid developments in semiconductor technology, the role of inductive components as a limitation for further improvements became clear. The challenges involve the magnetization losses and unwanted eddy currents at higher switching frequencies, which in turn limit the reduction of device volumes. New materials and design approaches offer solutions. Furthermore, new topologies of power converters in connection with flexible digital controls and design of magnetic components offer ways to reduce the required component volume and increase the power density, which is especially...

Power Line Communication Systems for Smart Grids presents the fundamentals and principles behind narrowband and broadband PLC technologies, covering the particularities of coupling PLC signals to the electrical grid and the main modulation and coding techniques used, to their standardisation and use in monitoring and control operations involved in energy management, charging of electric vehicles and distributed generation, taking into account the use of intermittent renewable energy sources.

This second edition offers substantial updates and new content. Chapters cover...

The potential of wave power lies in waves' kinetic energy. Waves have a far greater energy density than wind or solar and can generate between 24-70 kW per meter of wave. The global tidal energy potential is estimated to be 3 TW, with approximately 1 TW in comparably shallow waters. The challenge for the development of marine energy converters (MEC) is to achieve an investment cost and rate of return that will make marine energy devices viable, compared to other sources of electrical power.

The first edition of this work provided a description of the reliability and availability...

Microgrids are essential components of next-generation energy grids. A microgrid is a local, integrated energy system comprising interconnected loads and distributed energy resources; they can represent urban or rural districts, islands or local communities. Microgrids can operate in parallel with the main grid or independently in an intentional island mode. When on-site generation is included, intelligent buildings can also function as microgrids. Efficient optimization and control algorithms are crucial for ensuring optimal microgrid performance, making them a continuous focus of...

Hydrogen is a key vector towards a future sector-coupled and more integrated energy system. Hydrogen can be used as long term, even seasonal, storage for electricity itself, as well as a fuel in the transport and residential sectors, and as a feedstock for the chemical industries.

There are several competing, or complementary, technologies for generating hydrogen from various sources, and then to store it, to transport it, and to use it in various sectors. This book offers an overview of the currently available technologies, taking into account their principles, advantages and...

Emerging low-emission energy systems will depend on a range of energy vectors or fuels, for electricity, heating, storage and transport. Each has advantages and shortcomings, qualifying it for certain roles and applications. Liquid ammonia offers a higher energy density than liquid hydrogen.

This book covers trends, developments and advances in research around ammonia combustion systems. It is suitable for engineers, researchers and technicians working with ammonia or hydrogen in combustion systems, as well as for advanced students, especially PhD and MSc students in related...

The electrification of the economy entails the development and optimization of efficient electrical machines. Permanent magnet machines use permanent magnets, rather than windings, for field excitation. They are more efficient than other electrical machine technologies for high-efficiency applications. Multiphase machines, as compared to 3-phase machines, have advantages including lower torque pulsation, higher power density, and better fault tolerance.

This book offers concise and systematic coverage of multiphase permanent magnet machines and control techniques. It gives an...

The reliability of power electronic systems is a major concern because these systems are exposed to harsh environments, high stresses, and variable loads caused by the increasing proliferation of renewable power generation.

Real-time monitoring of aging and performance is becoming increasingly important. Monitoring the performance of power electronic devices helps identifying potential problems before they cause system failure, thus increasing the reliability and longevity of these systems.

This second edition follows new developments in converter and power electronics research...

A flexible AC transmission system (FACTS) provides a structured method to augment the transmission capabilities of conventional electrical energy systems. It is intended to enhance controllability, reliability and transfer capability using power electronic equipment and control techniques. HVDC are high voltage direct current systems. Both systems complement each other, they each have their specific area of application, and they can work together, in a coordinated fashion, for example, to accommodate growing shares of renewable energy such as wind power, which needs to be transferred over...

The use of advanced technologies is enabling the transformation of power grids to intelligent smart grids with real-time control and monitoring and integration of distributed renewable generation. With the development of phasor measurement units (PMUs) and the availability of real-time measurements, it has become possible to develop different power system applications to enhance stability and perform state estimation, load estimation, power network protection, and wide-area security assessment and reliability of the power grid.

This second edition of Synchronized Phasor...
