Research of Photovoltaic System MPPT Control Based on Improved Conductance Increment Method

In order to quickly and stably track to the maximum power point of the photovoltaic cell,a photovoltaic cell maximum power point tracking method is put forword which based on Conductance Increments method on the photovoltaic power generation system.This method uses Constant Parameter method away from the maximum power point,uses Conductance Increment method at the maximum power point.Through simulation studies,this method can quickly and accurately find the maximum power point according to the rapid changes in the external environment,and reduce the power oscillation phenomeno at the maximum power point,has a good practicability.
