Modeling and Control of a Photovoltaic Generator Using MPPT Regulator

In this paper, we study the performance of photovoltaic generators (PVG) controlled by Maximum Power Point Tracking (MPPT) algorithm, using a DC/DC converter (Boost) and batteries. We develop the mathematical model of the photovoltaic cell and of the photovoltaic generator and their electrical models. Also, we present the new battery model which we used in our simulation. We present the electrical model of the DC/DC convertor, and introduce the MPPT control algorithm PO (Perturbation and Observation). The simulation results obtained with this algorithm has shown good performances of our PVG regarding to its easy implementation and the low cost, and provide also a permanent supply
