The rising share of photovoltaic (PV) energy requires sophisticated digital techniques for control, monitoring and integration with the grid. In remote areas, where no trained personnel might be nearby to intervene, such technologies are vital to ensure reliability and power quality, and to harness the solar potential of these locations. Moreover, tracking is necessary for moveable systems. Digital technologies can be used to enable and augment the use of PV energy in the grid, as well as for desalination, water pumping and hydrolysis.

Phasor measurement units (PMUs) provide time synchronized measurements of phase angles of voltages or currents. These synchrophasors are used in electricity grids to support planning and operation. In the past decade, transmission network planners and grid operators have been using PMUs for monitoring applications. Improvements are still needed to realise the full potential of PMU data for more complex power systems with distributed renewables and increased loads. Challenges related to noise and higher frequency components from various dynamic behaviours of grid components, including...

The need to reduce greenhouse gas emissions and dependency on fossil fuels necessitates accelerated deployment of renewable energy, such as photovoltaics (PV). Regions with high insolation in the "Sun Belt" covering north Africa and the middle east, as well as in Australia, parts of Latin America, and elsewhere offer tremendous potential for PV, including for green hydrogen production. However, these regions are characterized by a hot climate and a dusty environment, both causing reduction of PV panel performance by 25% or more. The development of solar cells with enhanced resistance to...

The worldwide potential of electric power from tidal currents is potentially between 100 and 120 GW. The technology uses the ebb and flow currents off coasts to drive submerged turbines. The high load factor and the predictable resource characteristics make tidal energy an attractive, reliable power source. The technology is advancing rapidly towards maturity; several projects have now reached a relatively mature stage and are close to completion, but challenges remain. Topics for ongoing research include hydrodynamics and turbine design, as well as the power conversion interface...

Renewable energy is key to stopping climate change, however, the intermittent nature of most forms of renewable energy generation poses a challenge. Energy storage is therefore a focus of research and development, particularly for urban areas with their limited space and high population density, which results in massive demand for both small distributed and utility-scale generation. Such locations require thorough integration of storage, with the urban energy system treated as a whole, and sufficient planning, sizing and siting, and upgrades to the existing power grid hardware.

This...

The growing share of renewable energies, as well as the rising demand for electricity for transport and heating, are increasing the importance of power converters and the requirements for reliability and control. Intelligent control can increase converter efficiency, reducing size and weight. The application of intelligent control techniques to power converters has therefore recently become a focus of research.

Intelligent Control of Medium and High Power Converters summarizes the state of the art in the control of electric power converters. After an overview of the topic, the...

Lithium-ion batteries (LIBs) are key to storing clean energy. However, process design, including electrode processing, is critical for performance. There are many reviews addressing material development for LIBs, but comparatively few on correlating the material properties with processing design and constraints. While these technologies are becoming familiar in industry, they are not yet widely accessible to the research community.

This book provides a comprehensive and critical view of electrode processing and manufacturing for Li-ion batteries. Coverage includes electrode...

In modern power networks with high shares of renewable energy sources, and a mixture of alternating (AC) and direct current (DC) technology in different sections of the network, power switching devices are exposed to more and different stresses compared with those in conventional AC networks.

Another pressure on power switching equipment is to minimize their long-term environmental impact, for example, to relinquish the use of SF₆ with its high global warming potential. Solutions are either based on vacuum switching devices modified for higher voltages or on...

Power systems need to incorporate rising shares of intermittent renewables. The penetration levels of renewable energy sources, inverter-based resources and inverter-based loads have grown, which has negative impacts on the stability and system strength of existing power systems.

System strength describes the ability to manage fluctuations in supply or demand while maintaining the voltage. Metrics for the system strength and the hosting capacity are needed, as well as ways to improve the strength, for example by managing the loads, electric vehicles, generation and grid-forming...

Power transformers are static devices transferring electrical energy between two circuits with separate systems of alternating voltages, by means of electromagnetic induction. They are used to connect power networks and components with different voltage levels. Transformers are essential components for the transmission, distribution, and utilization of electric power in large power grids, which are facing increasingly demanding requirements for power quality, integration of renewable sources and demand side management. Transformers benefit from the recent technological developments in...
