Wind curtailment of power grid is severe during heating period in the ‘Three North’(northwest china, north china, and northeast china) area of China, and the ‘wind-heat conflict’ causes insufficient of power system peaking, which is one of the main reasons that impacts wind power consumption. To enhancing flexibility of power system by configuring flexible load is an effective means to improving wind power acceptance. This paper, based on the dispatch of the cogeneration unit, analyzed the composition and operation rules of battery energy storage–heat storage system. Considering the constraints of power system and thermal system, the coordinative dispatching model of battery energy storage and regenerative electric boiler is established. Based on a regional power grid in the ‘Three North’ area of China is used to simulate the acceptance of wind power under different modes of operation. The results show that in the way of power alternative, the regenerative electric boiler has the best effect of eliminating wind and abandoning wind, and the environmental benefits are obvious. When the thermal storage electric boiler is matched with an excessively large new adding heat load, the thermal power unit in the electric power for heating accounts for a relatively high amount of electricity, and the efficiency of energy utilization is low. Considering the battery storage price is greatly reduced, the peak shaving effect of battery energy storage and thermal storage electric boiler coordinated operation is the most obvious, and it is of great significance for the safe and stable operation of wind power and high-wind power infiltration grid.
