A Modified MPPT Method for Photovoltaic System

摘要：

　　The output of photovoltaic (PV) array is affected by the environmental factors such as irradiation and temperature,so an effective maximum power point tracking (MPPT) method of PV array is necessary.In this paper,a modified perturb and observe (MPO) method is proposed to achieve MPPT for a PV system and to improve the shortcomings of prior methods.Comparing with a typical perturb and observe (P&O) MPPT method,the MPO efficiency is improved in transient state by the proposed MPPT as theoretical prediction.
