Abstract: Aiming at the problem of wind abandonment caused by the contradiction between wind and heat

during the winter heating in the Three-north areas of China，a scheduling strategy for electric heating combined

system considering wind power consumption was proposed. Firstly，the "power determined by heat" constraints of

combined heat and power units was decoupled through the heat network interconnection on the source side，and the participation of comprehensive demand response resources was considered on the load side to assist in wind power consumption. Secondly，the multi-time scales scheduling model of the electric heating combined system was

established by considering various constraints，aiming at the lowest total system operation cost in the day before day and the lowest system regulation cost in the real-time stage. Finally，the experimental results of an example show that the proposed scheduling strategy can effectively improve the wind power consumption level and economy of the electric heating combined system.
