Special Issue Information

Dear Colleagues,

Advanced power electronic converters including modular converters have received an increased amount of attention from academia and industry in the areas of renewable energy, motor drives and energy storage systems. The development of these power converters will determine the future of electric vehicles (EVs) in terms of their propulsion systems as well as battery chargers, along with solar photovoltaic (PV) systems as well as wind energy systems.

In renewable energy systems, power converters are required to increase the efficiency in order to reduce the total power losses, improve the controllability and increase the reliability of the full system by providing support to the grid and fault-ride-through capability. In EVs, improving the efficiency of the power converters is crucial for enhancing the performance of the cooling system, providing increased travel range and improving the battery charger and management system.

This Special Issue is focused on developing new and efficient circuit configurations, modulation schemes and control strategies of advanced power electronic converters which can contribute to the future of renewable energy systems, as well as EVs. Specific topics of interest include, but are not limited to, the following:

Modular converters for EVs, PV, or wind energy systems.
High-power density converters for EVs and/or renewable energy systems
Design of high-frequency transformers in DC/DC and DC/AC power electronic converters.
Novel control strategies for advanced power converters in the context of EVs and/or renewable energy systems
High-power converters for EV chargers.
Accurate modelling of electrical systems comprising EVs, renewable energy systems, and the AC grid.
Advanced power converters employed in EV/PV/grid integration
Bidirectional converters for EV chargers and/or renewable energy generators with energy storage systems.
Improving the power quality of EV grid-connected chargers.
Control strategies for grid-connected renewable energy generators integrated with energy storage systems.
Advanced control strategies for battery management systems during driving, braking, and/or charging.

Abstract

Electric vehicles have become a crucial component of modern power systems, possessing substantial energy reserves that can be important power supplies in blackouts where the power grid has weak reserves or limited connections to other grids. In order to clarify the technical conditions and control methods of the centralized electric vehicle charging station as the black-start power source of the power grid, assuming that the centralized electric vehicle charging station can be considered a single, large-scale energy storage system, this paper proposes a three-stage coordinated recovery strategy based on the centralized electric vehicle charging station. The strategy involves three distinct stages, beginning with the establishment of AC frequency and voltage by the electric vehicle charging station to initiate the auxiliary load of the power plant. In the middle stage, considering the traditional generator has been connected, the charging station’s control mode is set to provide constant active and reactive power output, providing extra voltage and frequency support to the grid-connected generating units and crucial loads. Finally, in the later stage, control strategies are tailored to the charging power stations’ capacities, with one group of additional oscillation damping controllers, while the other group adopts additional frequency control to decrease power disturbances, ensuring a smooth recovery of the power grid. A PSCAD/EMTDC-based model was constructed to verify the proposed coordinated grid recovery strategies. The results demonstrated that the centralized station successfully established the voltage and frequency of the AC system, and the designed additional controller also made the recovery process much more stable.

by Abdulkarim Athwer and Ahmed Darwish

Abstract

This paper presents a comprehensive review on the employment of wide bandgap (WBG) semiconductor power devices in wind energy conversion systems (WECSs). Silicon-carbide- (SiC) and gallium-nitride (GaN)-based power devices are highlighted and studied in this review, focusing on their application in the wind energy system. This is due to their premium characteristics such as the operation at high switching frequency, which can reduce the switching losses, and the capability to operate at high temperatures compared with silicon (Si)-based devices. These advantages promote the replacement of the conventional Si-based devices with the WBG semiconductor devices in the new modular converter topologies due to the persistent demand for a more-efficient power converter topology with lower losses and smaller sizes. The main objective of this paper was to provide a comprehensive overview of the WBG power devices commercially available on the market and employed in the modular converter topologies for renewable energy systems. The paper also provides a comparison between the WBG power technologies and the traditional ones based on the Si devices. The paper starts from the conventional modular power converter topology circuits, and then, it discusses the opportunities for integrating the SiC and WBG devices in the modular power converters to improve and enhance the system’s performance.
