In order to solve the problem of the coupling characteristics of traditional cogeneration units and the problem of wind disposal and consumption during the winter heating period, a strategy of wind disposal and consumption with the combined operation of carbon trading with heat storage cogeneration units and electric boilers is proposed in this paper. Firstly, the combined operation of heat storage equipment, electric boilers and CHP units is used to meet the required heat load of the system, thus improving the electric peaking capacity of CHP units. Secondly, in order to further control carbon emissions, a stepped carbon trading and optimized electric boiler operation model is introduced to take into account the system operation cost, wind disposal consumption and carbon emissions, and a carbon trading model is constructed and solved for CHP-heat storage and electric boiler wind power consumption. Finally, the results of IEEE-30 node example show that the proposed strategy can effectively promote wind power consumption, reduce carbon emissions and effectively reduce system operating cost.
