Seeking Control (ESC): A review and a new GMPPT ESC scheme Nicu Bizon University of Pitesti, 1 Targu din Vale, Arges, 110040 Pitesti, Romania University Politehnica of Bucharest, 313 Splaiul Independentei, 060042 Bucharest, Romania [email protected], [email protected] Abstract: The objective of this paper is to present a survey of the Perturbed-based Extremum Seeking Control (PESC) methods and their applications in Photovoltaic (PV) arrays under Partially Shaded Conditions (PSCs). A new PESC scheme is also proposed to seek and track the Global Maximum Power Point (GMPP) of the PV power. This scheme has better performance than other GMPP methods and it may revive the specialists’ interest in applying this PESC scheme in PV applications and others multimodal problems from industry. Different PV and nonlinear multimodal patterns were used to test the proposed control scheme. The results obtained have shown very good performance related to search speed and tracking accuracy of the GMPP under different PSCs simulated.

Partial shading (PS) is an unavoidable condition which significantly reduces the efficiency and stability of a photovoltaic (PV) system. With PS, the system usually exhibits multiple-peak output power characteristics, but single-peak is also possible under special PS conditions. In fact it is shown that the partial shading condition (PSC) is the necessary but not sufficient condition for multip...
