Optimum LQR Switching Approach for the Improvement of STATCOM Performance

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 150)


Static Synchronous Compensator (STATCOM) is a device capable of solving the power quality problems in 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, an optimum Linear Quadratic Regulator (LQR) switching approach for STATCOM control is introduced to improve the performance by achieving the optimum performance between peak overshoot and settling time. Results are compared with the earlier conventional LQR approaches.
