, 50% backup for 1,500kWh/day load = 750kWh storage needed. Determines the required power output and inverter capacity. Most LFP batteries allow 90–95% DoD. Required capacity = usable energy / DoD factor. The simulation model developed for this study is a digital twin of the microgrid, incorporating components such as the BSS, renewable energy sources (wind and photovoltaic), second-life battery storage, and utilities. By optimizing energy flows within this model, considering the cost-effectiveness. The load is calculated by enumerating all appliances together with their power ratings and operational hours, thereafter adding these values to derive the total average energy demand in watt-hours or kilowatt-hours. It is preferable to enumerate both AC and DC loads individually, as inverter sizing. Battery Energy Storage System (BESS) sizing is the process of determining the appropriate energy capacity (kWh or MWh) and power rating (kW or MW) required for your specific application. Whether for residential backup, commercial peak shaving, or grid-level flexibility, proper sizing ensures system.
