An optimal control strategy devoted to manage the daily charging/discharging profiles of energy storage systems (ESSs) is described in the present paper. The proposed approach aims at minimizing microgrids (MGs) daily electricity costs considering both the real-time prices evolution and the effects of a significant presence of intermittent RES generation. Referring to MGs and electricity market modeling, which takes into account their main physical and economic constraints, an ESS charging/discharging strategy has been developed. The effectiveness of the proposed ESS management is verified on a MG case study.

Abstract

An optimal control strategy devoted to manage the daily charging/discharging profiles of energy storage systems (ESSs) is described in the present paper. The proposed approach aims at minimizing microgrids (MGs) daily electricity costs considering both the real-time prices evolution and the effects of a significant presence of intermittent RES generation. Referring to MGs and electricity market modeling, which takes into account their main physical and economic constraints, an ESS charging/discharging strategy has been developed. The effectiveness of the proposed ESS management is verified on a MG case study. The measurements of the MG demand and RES production are used to simulate and compare the daily MG electricity costs and energy balances with and without the proposed ESS optimal control.
