Active/Reactive Power Control of Three Phase Grid Connected Current Source Boost Inverter Using Particle Swarm Optimization

Abstract

PID control is the most common and simplest control method used for system control. However, selecting PID control coefficients for an optimal performance in power system applications is a central problem that few have addressed. Here, we propose the use of the particle swarm optimization (PSO) method to search for the optimal parameters of a PI controller. We applied this method to design an optimal PI controller for active and reactive power in a three phase grid connected current source boot inverter (CSBI). Simulation results show that our PSO-PI parameters selection method leads to better performance. © Springer International Publishing Switzerland 2015.
