“…In this context, the randomness and volatility associated with wind and PV affect the safe and stable operation of power grids [3][4][5]. Studies have shown that when wind and PV operate together, there is a complementary load output that can reduce the regulation pressure on the power system [6][7][8]. However, as the installed capacity of wind and PV systems increases, there is still a need to enhance the flexibility of the power supply side and the capacity of the load side to maintain a balance between the power supply and load demand [9,10].…”

There is a growing need to explore the potential of coal-fired power plants (CFPPs) to enhance the utilization rate of wind power (wind) and photovoltaic power (PV) in the green energy field. This study developed a load regulation model for a multi-power generation system comprising wind, PV, and coal energy storage using realworld data. The power supply process was divided into eight fundamental load regulation scenarios, elucidating the influence of each scenario on load regulation. Within the framework of the multi-power generation system with the wind (50 MW) and PV (50 MW) alongside a CFPP (330 MW), a lithium-iron phosphate energy storage system (LIPBESS) was integrated to improve the system's load regulation flexibility. The energy storage operation strategy was formulated based on the charging and discharging priority of the LIPBESS for each basic scenario and the charging and discharging load calculation method of LIPBESS auxiliary regulation. Through optimization using the particle swarm algorithm, the optimal capacity of LIPBESS was determined to be within the 5.24-4.88 MWh range. From an economic perspective, the LIPBESS operating with CFPP as the regulating power source was 49.1% lower in capacity compared to the renewable energy-based storage mode.
