In terms of large scale wind power integrated into the power system.Based on the framework of regional energy system,a heat storage control method for thermal system is proposed in this paper.By introducing heat storage device and distributed heat pump this method can improve the operational flexibility of cogeneration unit and the peak regulation demand of wind power is met.At the same time,the distributed heat pump can further improve the peak regulation capacity of the system and improve the wind power consumption.Finally,considering the characteristics of building heat storage and human thermal comfort,it can improve the flexibility of heat storage control and realize the effective tracking of wind power fluctuation.The simulation results show the effect of heat storage control method on the peak regulation,and also analyze the influence on peak regulation of wind power with different heat load characteristics.
