Voltage Unbalance Compensation in Distribution Feeders Using Soft Open Points
Journal of Modern Power Systems and Clean Energy, 2022 Soft open points (SOPs) are power electronic devices that may replace conventional normally-open points in distribution networks. They can be used for active power flow control, reactive power compensation, fault isolation, and service restoration ...
