Modeling of full photovoltaic systems applied to advanced control strategies

Abstract

Nowadays, different control strategies, to regulate Photovoltaic (PV) maximum power point are available. This paper is focused on the modeling of PV power conversion chains considering the PV panel, its associated power conversion stage and the load as a sole system. Furthermore, two control strategies have been proposed for the resulting non-linear system. These controllers are calculated to mitigate input and load disturbances. In addition, the proposed model and its underlying control strategy is used with a P&O MPPT algorithm to show the feasibility in advanced control strategies for PV systems.
