Special Issue Information

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.

There are significant emissions of greenhouse gases into the atmosphere from the transportation industry. As a result, the idea that electric vehicles (EVs) offer a revolutionary way to reduce greenhouse gas emissions and our reliance on rapidly depleting petroleum supplies has been put forward. EVs are becoming more common in many nations worldwide, and the rapid uptake of this technology is heavily reliant on the growth of charging stations. This is leading to a significant increase in their number on the road. This rise has created an opportunity for EVs to be integrated with the power system as a Demand Response (DR) resource in the form of an EV fast charging station (EVFCS). To allocate electric vehicle fast charging stations as a dynamic load for frequency control and on specific buses, this study included the optimal location for the EVFCS and the best controller selection to obtain the best outcomes as DR for various network disruptions. The optimal location for the EVFCS is determined by applying transient voltage drop and frequency nadir parameters to the Particle Swarm Optimization (PSO) location model as the first stage of this study. The second stage is to explore the optimal regulation of the dynamic EVFCS load using the PSO approach for the PID controller. PID controller settings are acquired to efficiently support power system stability in the event of disruptions. The suggested model addresses various types of system disturbances—generation reduction, load reduction, and line faults—when it comes to the Kundur Power System and the IEEE 39 bus system. The results show that Bus 1 then Bus 4 of the Kundur System and Bus 39 then Bus 1 in the IEEE 39 bus system are the best locations for dynamic EVFCS. Full article

This study examined the design and optimization of low-speed external frame motors featuring Halbach-type and olive-shaped magnet structures to improve performance in spacecraft control moment gyroscopes (CMGs). Our research was driven by the urgent need for precise, high-torque, low-speed motors in CMGs, where conventional designs, including Halbach-type and traditional radial magnet configurations, are hindered by manufacturing complexity and excessive torque pulsation. This study focused on optimizing rotor pole configurations to enhance efficiency and torque stability. An olive-shaped magnet structure provides a more uniform magnetic field distribution in the air gap, substantially reducing magnetic field harmonics and minimizing cogging torque and torque pulsation—critical performance factors for low-speed applications. Comparative analysis reveals that the olive-shaped motor achieves a peak torque of 0.312 N·m with a torque pulsation of 0.9 mN·m, maintaining an amplitude below 0.3%. This demonstrates a 20% improvement compared to the Halbach-type motor’s torque pulsation of 1.15 mN·m. Moreover, the olive-shaped motor exhibits superior stability in air-gap magnetization under different loads, ensuring high efficiency and robust operation. By streamlining magnet assembly while enhancing electromagnetic performance, this study offers a cost-effective, high-precision solution for CMG systems. These findings underscore the olive-shaped magnet motor’s potential to advance motor technology for aerospace applications. Full article
