Research on control strategy of distributed power flow controller under low current condition

Distributed Power Flow Controller (DPFC) is a typical D-FACTS device for power flow control by distributed installation, which is installed on overhead transmission lines or substations. The voltage source converter (VSC) unit in DPFC is connected in series to the transmission line, which can adjust...
