The coordination of the user-side flexibility resources can help reduce the carbon emission and promote the optimized operation of the system.As for the day-ahead dispatch problem of the combined heat and power system,an optimized combined heat and power dispatch model considering decreasing carbon emission by the coordination of heat load elasticity and time-of-use demand response is established.In order to effectively fulfill the coordination potential of the user-side flexibility resources,the heat load elasticity of the building heating users is considered on the heat load user side,and the time-of-use demand response is considered on the electric load user side.The optimization function of the model consists of three parts including the system fuel cost,the system wind power curtailment penalty and the system carbon trading cost.Results indicate that the coordination of heat load elasticity and time-of-use demand response can effectively help decrease the carbon emission and promote the optimized operation of the combined heat and power system.
