Gale period and winter heating period are highly coincident in the three-north area of China. The operation mode of the thermal power heating unit is large and the peak load regulation capacity of power grid is inadequate, which causes serious wind power accommodation problems. In order to relieve the wind power accommodation problems in the three-north area, and to improve clean energy utilization rate, a heat and electricity joint dispatching platform in provincial power grid dispatching institution is proposed, which facilitates information interaction with customers of electric heat storage and heating by using internet. Through joint optimization dispatching of power and electric heat storage and heating, electric heat-storage equipment can be started during wind curtailment period, and electric heat storage and heating by wind energy curtailment can be realized. A trading strategy for electric heat storage by wind energy curtailment, which considers the economy of many sides, is also established which guarantees the economic interests of wind power enterprises and heating enterprises and promotes wind power accommodation and the sustainable development of electricity heating by wind energy curtailment.
