Abstract :Static Synchronous Compensator (STATCOM) is a self-tuning proportional-integral (PI) controller that has been developed to handle the voltage and reactive power of Cascaded H-Bridges (CHB-STATCOM) in order to improve the power system. The purpose of optimizing controller parameters for a Multilevel Converter-based STATCOM (Static Synchronous Compensator) in the context of reactive power compensation is to enhance the performance and efficiency of the STATCOM system in regulating the power factor and voltage of an electrical system. This controller was introduced in this article. This research presented that the STATCOM should have the capability to be operate both in inductive and capacitive mode of operation and absorb or injects the desired amount of reactive power into the grid. The reactionary power that is received or supplied contributes to the improvement of the power system. The benefits of the self-tuning PI controller have been optimized to their full potential through the use of Accelerated Particle Swarm Optimization (APSO) strategies. The STATCOM is implemented into the electrical system, and its reaction to varying reactive and voltage levels is analyzed as part of the process of determining whether or not the optimization techniques are successful. Two controllers are now in operation at the STATCOM. The first controller is in charge of managing the DC voltage (which is employ me to produce reference signal depended on differences in phase angle), and the second controller is in charge of controlling the reactive power. Both controllers are in use at the same time. (Which is what is utilized to produce the modulation index). The output of the controller is then transferred to the phase change carrier, which is followed by pulse width modulation in a sinusoidal pattern. Because of this, the power converter switch may now function properly.
