A Novel Hybrid Control for Maximizing Power in a Photovoltaic System

Abstract
This article is devoted to the development of a hybrid algorithm to track the maximum power in a photovoltaic system using a multicellular converter. The requirements of Maximum Power Point Tracking (MPPT) can be summarized in a fast transient and a minimal oscillation at the maximum power point (MPP). This can be met in two steps by using the hybrid systems theory: i) a hybrid transient automaton, that ensures a fast convergence by a minimal settling time and low number of commutations, and ii) a hybrid steady-state automaton that guarantees the minimum stress around the MPP. To justify a hybrid MPPT as a viable MPPT option, a comprehensive comparison is carried out between the proposed MPPT and the two methods; the Perturb and Observe (P & O) and the Incremental Conductance (IC). The results show that the hybrid MPPT is capable of tracking the MPP with higher performance under various types of environmental changes.
