This paper studies the feasibility of a supply-side wind-coal integrated energy system. Based on grid-side data, the load regulation model of coal-fired power and the wind-coal integrated energy system model are established. According to the simulation results, the reasons why the wind-coal combined power supply is difficult to meet the grid-side demand are revealed through scenario analysis. Based on the wind-coal combined operation, a wind-coal-storage integrated energy system was proposed by adding lithium-iron phosphate battery energy storage system (LIPBESS) to adjust the load of the system. According to the four load adjustment scenarios of grid-side instructions of the wind-coal system, the difficulty of load adjustment in each scenario is analyzed. Based on the priority degree of LIPBESS charge/discharge in four scenarios at different time periods, the operation mode of two charges and two discharges per day was developed. Based on the independent operation level of coal-fired power, after the addition of LIPBESS (5.5 MWh), the average qualified rate of multi-power operation in March and June reached the level of independent operation of coal-fired power, while the average qualified rate of the remaining months was only 5.4% different from that of independent operation of coal-fired power. Compared with the wind storage mode, the energy storage capacity and investment cost of wind-coal-storage integrated energy system are reduced by 54.2% and 53.7%, respectively.
