Survey of Maximum Power Point Tracking Techniques for Photovoltaic Power System

In the photovoltaic power generation system, the output characteristics of photovoltaic cells has obvious nonlinear characteristics and its output characteristics cell is primarily affected by the lighting intensity and air temperature. It is neccessary to track rapidly and accurately control of the maximum power point of photovoltaic cells in order to improve the utilization efficiency of photovoltaic cells. A dozen used in commonly the principle of photovoltaic cell maximum power point tracking control method is introduced in the paper, discussing advantages and shortcoming of individual method. The developing prospect o f the MPPT method is discussed finally.
