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.
