Energy management control strategy for stand-alone photovoltaic system

An energy management control strategy for a stand-alone photovoltaic system is presented in this paper. The system consists in a photovoltaic panel connected to a Boost converter, an auxiliary battery powered by a bidirectional Buck-Boost converter and a resistive load. The purpose of this control strategy is to keep the Dc-link voltage on a reference value under load variations and changes in the panel conditions. The proposal system is validated with simulation results.
