ABSTRACT

Distributed Power Flow Controller (DPFC) is one of the most powerful and economical devices in flexible AC transmission system. It has the ability to adjust the reactance, voltage, power and other structural parameters and operation parameters of power system simultaneously or independently. It can improve the transmission capacity of power grid and enhance the stability of power system. The network has broad application prospects. In this paper, based on the theory of fuzzy control, the fuzzy PI control is applied to optimize the design of distributed power flow controller. Firstly, the structure and principle of DPFC are analyzed; secondly, the fuzzy PI parameters are designed by using the fuzzy control theory; finally, the simulation results are verified by using Power System Analysis Software Package (PSASP). The results show that the fuzzy PI control can effectively improve the speed and scope of DPFC power flow control.
