3.5-kW 94.2% DC–DC Efficiency Capacitive Power Transfer With Zero Reactive Power Circulating

IEEE transactions on power electronics, 2023
Most existing capacitive power transfer (CPT) circuits are developed from basic series–series CPT compensation, which have a common drawback of unavoidable reactive power circulating from the primary side of the capacitive coupler to its secondary side ...

A Novel Droop Control Strategy of Reactive Power Sharing Based on Adaptive Virtual Impedance in Microgrids

IEEE transactions on industrial electronics (1982. Print), 2022
Droop control strategy is widely used to control parallel inverters in a microgrid. However, due to the mismatched line impedance, the traditional droop control strategy is difficult to evenly share the reactive power and restrain the circulating current

A Distributed MPC to Exploit Reactive Power V2G for Real-Time Voltage Regulation in Distribution Networks

IEEE Transactions on Smart Grid, 2021
It has been demonstrated theoretically and experimentally that the Vehicle-to-Grid (V2G) enabled electric vehicle (EV) charger is of a reactive power compensation ability with a battery or capacitor connected. To exploit the aggregated reactive power V2G

Reactive Power Market Demonstration

2021 International Conference on Smart Energy Systems and Technologies (SEST), 2021
The network operators in Finland are facing new challenges in reactive power control. This paper focuses on the reactive power flow at the TSO/DSO interface. The motivation is to add the control ability of reactive power by a market-based approach where so far untapped flexible inverter-based resources connected to the distribution system are used as ...

Grid-Synchronization Stability Analysis and Loop Shaping for PLL-Based Power Converters With Different Reactive Power Control

IEEE Transactions on Smart Grid, 2020
Power converters may lose synchronization with the remaining network when integrated in a weak power grid. Such an instability phenomenon [known as grid-synchronization instability (GSI)] features the frequency divergence of phase-locked loop (PLL) and ...
