Reserch on Multi-mode Operation of Distributed Power Flow Controller

With the continuous increase in electricity demand and the common problems of centralized FACTS, such as high cost, large operating loss, and low reliability. The Distributed Power Flow Controller (DPFC) technology, which has the advantages of cost-effectiveness and reliability, is developing rapidly, but the DPFC in the current research only works in a single control mode. This paper introduces the basic principles of DPFC multi-mode operation based on typical systems, studies the control principles and control ability of DPFC under different control modes; proposes the multi-mode control strategy of DPFC and presents the electromagnetic transient model of DPFC based on PSCAD/EMTDC, the simulation verifies the validity and reliability of the DPFC multi-mode operation strategy.
