Abstract
Soft open point (SOP) is a new power electronic device installed in distribution network to replace the normally open point (NOP), which can achieve normalized closed-loop operation of distribution network. This paper proposes a multi-port coordinated control strategy of SOP to achieve the power flow regulation and power quality improvement of distribution network under steady state operation. The proposed strategy can improve the power quality while balancing the active power among feeders with the SOP. Three-port back to back MMC SOP is taken as studied case. Simulation results verify the effectiveness of the strategies adopted.
