“…An energy storage system (ESS), which is connected to a grid to store energy during the absence of power generation, is crucial for addressing such problems [5]. Recently, ESSs using lithium-ion batteries (LIBs) have become popular, and are expected to be key in addressing issues such as sudden blackouts caused by unstable power supplies or for control of the power demand [6][7][8][9]. In the case of reclaimed land and reservoirs that are suitable for large power generation (around 100 MW), there have been challenges in connecting the power generation facilities to the main power grid.…”

This work is a case study of 905 households, to present methods for optimizing the capacity of photovoltaic sytems (PVs)/energy storage systems (ESSs) for household to reach a desired energy self-sufficiency (70% to 90%). In order to calculate the capacity of PV and ESSs that would enhance the energy self-sufficiency of families in rural areas, the solar radiance data of the target area for the last five years and the average monthly power usage in the previous year were collected. Then, households with an average energy consumption of 250 kWh per month were chosen for this research. According to the simulation done using Solar Pro, the optimized capacities of PVs and ESSs are 2.67 kW and 7.15 kW, respectively, in order to achieve 90% energy self-sufficiency. We visualized the change in the optimum capacity of PVs and ESSs for the desired energy self-sufficiency. This study would be the base work for forming a grid-distributed energy network system by expanding the system to a national scale.
