Optimal energy management of a photovoltaic stand-alone dual battery system

Abstract

The paper introduces a new optimal energy management method for photovoltaic stand-alone dual battery systems. The method exploits a predictive state of charge (SOC) model to implement the control algorithm. To validate the proposed algorithm a stand-alone photovoltaic system has been modeled. Finally, Monte Carlo simulations based on a probabilistic model of the solar radiation have been performed. The results have shown the validity of the proposed control strategy over other methods based on voltage control only.
