A pole placement controller for CSC based STATCOM with genetic algorithm

Abstract

Flexible AC Transmission Systems (FACTS) devices have been used in power systems since the 1970s for the improvement of its dynamic performance. Among these devices, Static Synchronous Compensator (STATCOM) is a shunt connected FACTS device, which is capable of providing reactive power compensation to the power system. STATCOM is a multiple input and multiple output system. In this paper, the CSC based STATCOM is controlled by the pole placement. But the best constant values for pole placement controller's parameters are laboriously obtained through trial and error, although time consuming. So the genetic algorithm (GA) is employed to find the best values for pole placement controller's parameters in a very short time. These methods are tested in MATLAB, and their results are obtained. The simulation results show an improvement in input-output response of CSC-STATCOM.
