Computational analysis of battery operation in photovoltaic systems with varying charging and discharging rates

In the case of a mass introduction of PV the instability of PV system output leads to a deterioration of power quality in the distribution system. In this research, we focus on the storage battery operation to achieve a balance between power supply and demand, and perform multi-objective optimization. Specifically, we determine the optimal relationship between the storage battery's charging and discharging rates and the required time resolution for ideal optimization results.
