However, the configuration of energy storage for household PV can significantly improve the self-consumption of PV, mitigate the impact of distributed PV grid connection on the distribution network, ensure the safe, reliable and economic operation of the power system, and have good environmental and social benefits.
The government can formulate appropriate energy storage subsidies or incentive policies to reduce the investment and operating costs of household PV storage system, so as to effectively improve the economic benefits of rural household PV storage system. Innovate and improve the market-oriented transaction mode of distributed generation.
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.
