Thus, the peak shaving operation of the ESS aims to reduce the demand charge of the load by reducing the maximum peak demand (max_load(n)) during the mid-peak and on-peak periods. The charging cost may increase in this process due to ESS charging in the off-peak period; however, it is offset by the arbitrage profit, which occurs …
