Improvement of STATCOM Performance with Optimum LQR and Pole placement Controller Based on Genetic Algorithm

Static Synchronous Compensator (STATCOM) is a device capable of solving the power quality problems at the power system. These problems happen in milliseconds and because of the time limitation; it requires the STATCOM that has continuous reactive power control with fast response. In this paper, a LQR (Linear Quadratic Regulator) and Pole placement method for STATCOM control is introduced. The former controller designing needs to positive definite matrix selection and the later is relative to desired pole places in complex coordinate. In this article, matrixes coefficients and dominant poles of closed loop transfer function are selected based on Genetic algorithm method. These methods are tested in MATLAB, and their results are obtained.
