Large-scale PV grid-connected power generation system put forward new challenges on the stability and control of the power grid and the grid-tied photovoltaic system with an energy storage system.
In the design of the “photovoltaic + energy storage” system construction scheme studied, photovoltaic power generation system and energy storage system cooperate with each other to complete grid-connected power generation.
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.
A 50 MW “photovoltaic + energy storage” power generation system is designed. The operation performance of the power generation system is studied from various angles. The economic and environmental benefits in the life cycle of the system are explored. The carbon emission that can be saved by power generation system is calculated.
Through the feasibility verification of the model control mode and the strategy control, the grid-connected PV system combined with reserve battery storage can effectively improve the stability of the system and reduce the cost of power generation.
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.
