Active Voltage and Frequency Support Control by the EV, New Energy and Energy Storages, 2nd Edition

Dear Colleagues,

With the proposal of the ‘carbon peak’ and ‘carbon neutrality’ policies, constructing a new type of renewable-integrated power system has become the main direction of future development. In this context, large-scale renewable energies are integrated into power systems through powered electronic devices, bringing a series of new frequency and voltage characteristics, i.e., reduced inertia, weakened frequency regulation ability, and fast voltage dynamics, which are different from traditional power systems. Frequency and voltage stability has gradually become an important factor restricting the increase in the penetration rate of renewables in power systems. However, the abundant controllable resources, such as EVs and renewable energies, supply sufficient regulation space. Moreover, the high controllability and flexible power control methods of power electronic devices can provide new ways for system frequency control. This Special Issue, ‘Active Voltage and Frequency Support Control by the EV, New Energy and Energy Storages, 2nd Edition’, aims to explore the potential of electric vehicles (EVs) and new energy sources in providing frequency and voltage support and virtual inertia to the power grid. The displacement of conventional generation via converter-connected resources reduces the available rotational inertia in the power system, which leads to faster frequency dynamics and less-stable frequency behavior. EVs can represent a reliable solution for enhancing frequency stability due to their fast response and ability to provide a large amount of aggregated power. New energy sources such as wind and solar can also contribute to frequency regulation by adjusting their output according to grid conditions. Energy storage systems can be used to store excess energy and release it when needed to balance supply and demand. This Special Issue invites original research papers that address the challenges and opportunities of frequency support control using EVs and new energy sources, such as the following:

• Modeling and analysis of voltage/frequency dynamics in low-inertia power systems.
• Design and implementation of innovative control algorithms, such as grid-forming control, for EVs and new energy sources to provide virtual inertia, damping, and voltage frequency support.
• Control design for synchronization stability improvement using EVs and new energy sources.
• Coordinated control of EV charging stations, grid-tied inverters, and energy storage systems for grid voltage and frequency support.
• EV, new energy, and energy storage integration-based power electronic transformers: design and control.
• EV, new energy, and energy storage integration-based AC/DC micro-grid.
• Impact assessment of EVs and new energy sources on grid frequency stability and reliability.
• Optimization and management of EVs and new energy sources for frequency support.
• Case studies and experimental validation of frequency support control using EVs and new energy sources.

This Special Issue welcomes papers that present novel theoretical, computational, or experimental results that advance the state of the art in frequency support control using EVs and new energy sources.
