Improved Droop Control Method for Reactive Power Sharing in Autonomous Microgrids [PDF]
Journal of Renewable Energy and Environment, 2022 Conventional droop control method has been widely adopted for power sharing between Distributed Generators (DGs) in microgrids. However, the mismatched feeder impedance of the Voltage-Sourced Inverters (VSI) may generate reactive power sharing error ...

Optimized Reactive Power Control of Module Power Imbalance of Cascaded Converter
IEEE Open Journal of Power Electronics, 2022 In the medium voltage cascaded converter, the power imbalance problem among the converter modules will result in certain converter modules over-modulated. Reactive power control (RPC) scheme is an effective way to balance the cascaded converters.
