Customer ServiceIn addition, in order to further improve the energy utilization rate and economic benefits of household PV energy storage system, practical and feasible targeted suggestions are put forward, which provides a reference for expanding the application channels of distributed household PV and accelerating the development of distributed energy.
According to the “Research Report on Household Energy Storage Industry” (2022), the life cycle of energy storage is 10 years, the unit capacity cost is 175 $/kWh, and the unit power cost is 56 $/kW. The installation cost of energy storage has been included in the initial investment.
Configurating energy storage for household PV is friendly to the distribution network. Household photovoltaic (PV) is booming in China. In 2021, household PV contributed 21.6 GW of new installed capacity, accounting for 73.8 % of the new installed capacity of distributed PV.
The operation mode is that the PV is self-generation and self-consumption, and the surplus PV power is connected to the grid. According to the optimized configuration results of energy storage under the grid-connected mode, the detailed operation of the household PV storage system in each season in Scenario 4 is shown in Fig. 21, Fig. 22, Fig. 23.
Residential loads and energy storage batteries consume PV power to the most extent. If there is still remaining PV power after the energy storage is fully charged, it is connected to the power grid. When the PV output is insufficient, the energy storage battery supplies power to the residential loads.
Yuan et al. proposed a PV and energy storage optimization configuration model based on the second-generation non-dominated sorting genetic algorithm. The results of the case analysis show that the optimized PV energy storage system can effectively improve the PV utilization rate and economy of the microgrid system.
