In order to achieve maximum utilization efficiency of photovoltaic energy, photovoltaic power generation system usually requires maximum power tracking control. Since the maximum power point vary with solar insolation and cell temperature, it is difficult to track the maximum power point for the various insolation and temperature levels.<br>In this paper, it is shown that the derivative (<i>dp</i><sub>s</sub>/<i>de</i><sub>s</sub>) of output power (<i>p</i><sub>s</sub>) with respect to output voltage(<i>e</i><sub>s</sub>) of photovoltaic array is equal to zero at maximum power point. This kind of relationship is independent on the insolation and temperature. So, when the insolation or/and temperaturevarious changes, the corresponding maximum power point can be simply obtained by only controlling its derivative <i>dp</i><sub>s</sub>/<i>de</i><sub>s</sub> toward zero. Based on this concept a maximum power tracking control method is proposed and is complemented with the boost chopper in an utility interactive photovoltaic power generation system. The maximum power tracking control system is constructed and the relating design method is described. It is shown that the presented control system has a high stability to a wide change range of insolation and temperature. Finally, the validity of the proposed method is verified through simulations and experiments.
