Abstract: Aiming at the multi peak output characteristics of photovoltaic array caused by local shadow,the traditional single peak algorithm has been unable to apply. In order to find the global optimal solution,a MPPT control algorithm based on multi universe optimization algorithm is proposed. The principle of multi universe optimization algorithm is easy to understand,and the parameter setting is simple,so it is convenient to apply in the multi peak MPPT module of photovoltaic power generation. Through simulation analysis,it is proved that MPPT control model based on multi universe optimization algorithm can achieve global maximum power point tracking in a short time. The algorithm can be combined with other algorithms to further improve the optimization efficiency of the algorithm,which has important guiding significance for photovoltaic MPPT multi peak optimization algorithm,and also has technical and theoretical reference value for engineering practice.
