| Abstract: | In order to overcome the defects of perturbation and observation(P&O)method and fixed-parameter method,this paper presents a dual-mode maximum power point tracking(MPPT)control method,which combines the short-cir-cuit current method and the P&O method.The method can be to track the real maximum power point for rapidly changing insolation conditions and reduce the energy cost availably.It is proved experimentally and through simulation results that the method has good performances and can effectively elimina... |
