摘要
Abstract
The output characteristic curve of PV array is presented with multi peak characteristics under the shadow conditions.The existing online MPPT method has a long tracking time,and the voltage fluctuation is large in the tracking process,which is easy to cause the array mismatch.In order to solve this problem,a hybrid MPPT algorithm based on model prediction is proposed,and the preliminary optimization process is put into the software,through the process of "detection-prediction process-reoptimization" to complete the MPPT of multi peak condition.Simulation results show that compared with the existing MPPT method,a hybrid MPPT algorithm based on model prediction can effectively shorten the search time of the system,and the voltage fluctuation is smaller,which is suitable for the maximum power tracking of photovoltaic array under the shadow condition.关键词
