Power-Supporting Operation of Energy Storage for Energy-Independent Housing Complex

This paper proposes an energy storage operation method that reduces power-consuming time by avoiding net power consumption in an energy-independent housing complex composed of multiple houses and photovoltaic power generation. The energy storage charges energy generated from the photovoltaic power generation in the housing complex during the day and compensates for power consumption at night using the stored energy. The function of the energy storage was verified through simulation developed in Python. In addition, through a real 56 kW photovoltaic power plant and an energy storage with a power capacity of 25 kW and a battery capacity of 114 kWh, about 21 hours of positive grid power per day was achieved on average during an operating period of 35 days.
