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.
It is shown that residential PV prosumers can contribute up to 5.5% of the total power generation by 2050, with a global installed capacity of around 2 TW ( Ram et al., 2017a, Breyer et al., 2018 ). Regional variation of the installed capacities as well as generation shares of residential PV prosumers is shown in Fig. 17.
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.
The results show that the configuration of energy storage for household PV can significantly reduce PV grid-connected power, improve the local consumption of PV power, promote the safe and stable operation of the power grid, reduce carbon emissions, and achieve appreciable economic benefits.
In 2021, household PV contributed 21.6 GW of new installed capacity, accounting for 73.8 % of the new installed capacity of distributed PV. However, due to the randomness and intermittency of PV power generation, large-scale household PV grid connection has a serious impact on the safe and stable operation of the distribution network.
