Adaptive Integral-Proportional Controller in Static Synchronous Compensator Based on Genetic Algorithm

چکیده
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 way, optimal exploitation of STATCOM by classical controllers has been a controversial issue in reputable journals. One of the most common controlling devices in the market is the Integral-Proportional (IP) controller. In this article, the STATCOM is controlled by IP controller. The best constant values for IP controller's parameters are laboriously obtained through trial and error, although time consuming. Genetic algorithm is employed to find the best values for IP controller's parameters in a very short time. The simulation results show an improvement in current control response. These methods are tested in MATLAB, and their results are obtained. Key-Words: Genetic algorithm, IP controller, STATCOM.
