Pbestリセットを含むPSOとその動的最大電力点追従への応用

This paper presents a particle swarm optimizer algorithm for the maximum power point tracking　in time-variant photovoltaic systems. In order to avoid trapping into local optima, the algorithmaccelerates periodically velocity of particles. In order to follow the time-variant characteristics, the optimizer uses a flexible renewal method of the personal best. The algorithm uses onlyone particle and sampled values of the particle position at several time steps are used as plural particles in real environment. Performing basic numerical experiments, the algorithm efficiencyis investigated.Key Words : particle swarm optimization, maximum power point tracking, photovoltaicsystem
