Abstract

The output characteristics of photovoltaic cells varies with the load and the external environment.In order to improve the conversion efficiency of PV cells , it is necessary to keep the system working in maximum power point(MPP) nearby.According to maximum power point tracking for PV systems,a new intelligent control method based on dynamic recurrent fuzzy neural network is proposed.The simulation results show that when the external environment changes ,the system can make rapid response and accurately track the maximum power point of PV cells.What's more,it has good control accuracy and stability.
