Abstract

A photovoltaic generator can operate over a wide range of voltage and output current, but it can deliver a maximum power only for particular values of the current and tension. Indeed characteristic I (V) of the generator depend on solar illumination and the temperature. These climatic variations involve the fluctuation of the point of maximum power. Because of this fluctuation, one often intercalates between the generator and the receiver one or more static inverters ordered allowing continuing the point of maximum power. In this paper, a maximum power tracking controller Sinusoidal Extremum-Seeking Control (ESC) is designed in an attempt to improve the system stability and robustness. Relative to the P&Q method, it demonstrates a superior overall efficiency [8] and well maintained robustness in the rapidly varying atmospheric.
