The optimization of control parameters of PSO based MPPT for photovoltaics

An effective PSO (Particle Swarm Optimization) of MPPT (Maximum Power Point Tracking) control method for photovoltaic(PV) power generation system was proposed in the past paper. In this paper, the authors propose the parameter tuning method of the controller based on an adjusting rule in order to extract power as large as possible under various insolation conditions with partial shading. In the result, PSO control makes PV output power increased.
