Maximum Power Point Search Strategy with Two Particle Swarm Optimizers for Photovoltaic Model

Abstract

This study applies a circuit solution detecting technique by the particle swarm optimization (PSO) to search the maximum power point (MPP) in the photovoltaic (PV) model. A task of the proposed method is to find system parameters which produce the maximum power, however, finding the MPP requires an information of the circuit solution. The proposed method consists of two PSOs that search the MPP and the circuit solution, respectively. We confirm that the proposed method can obtain the parameters with same accuracy as the exact calculation in a less amount of iterations.
