Based on the load data optimization results of the outer time-of-use electricity price model, with the goal of maximizing the on-site consumption rate of new energy and minimizing the cost of energy storage configuration, appropriate capacity and power are allocated for the energy storage equipment in the wind and solar storage system.
BESS = battery energy storage system, MW = megawatt, MWh = megawatt-hour, WACC = weighted average cost of capital. *Daily energy use = BESS power (20 MW) * capacity (5 MWh) * round trips per day (8 cycles) * DOD per round-trip (80%)/round trip eficiency (85%) = 37.65 MWh.
