The most attractive potential strategy of peak-load shaving is the application of the battery energy storage system (BESS) [21,22]. In this technique, peak shaving is achieved through the process of charging the BESS when demand is low and discharging it when demand is high, as shown in Fig. 1 [23].

PEAK SHAVING. Load shifting, or demand response, optimizes electricity use and can reduce energy costs. While similar to peak shaving, with its goal to relieve stress on the electric grid within peak demand periods, the way load shifting achieves this is different. Load shifting involves moving energy consumption from high-demand (peak
