Abstract

Distributed power flow controller (DPFC) can flexibly improve the transmission capacity of existing lines and thus reduce operation cost of power system

however

the introduction of DPFC increases difficulties and non-convexity of traditional optimal power flow (OPF) problem. A simplified steady-state power model of DPFC is proposed based on its structure and working principle. The feasible region of power flow for line with DPFC in actual power grid is given considering the capacity of series unit of device in operation. On this basis

the semi-definite programming (SDP) method

which is insensitive to the initial value

is extended to establish the optimal model of system with DPFC. And then the primal dual interior point method is used to solve the OPF problem. The test results show that the proposed method can solve the OPF problem with DPFC.
