The PV array maximum power point tracking in the shadow of conditions

The output of photovoltaic array has several corresponding local peaks of power-voltage curve with the existence of the shadow, In order to make the photovoltaic arrays continue to work in the maximum power point, need to create conditions for the model of the PV array, On the basis of the model, there are having some further detailed analysis and research about the characters of the local photovoltaic array under the shadow. A method was proposed which the maximum power point tracking of photovoltaic array, In order to achieve a novel method based on disturbance observed maximum power point tracking. This method is executed by DC-DC circuit which is controlled by the algorithm TMS320F28027 processor. To achieve maximum power photovoltaic (GMPP) output under complex conditions.
