With the development concept of “low-carbon economy”, both the emission reduction and energy conservation has comes the important development direction of power industry. In this context, we provide a CCHP microgrid optimal dispatching model that considers the integrated demand response and the carbon trading mechanism. This paper presents a carbon trading mechanism into the microgrid model that includes electricity-to-gas equipment. Posteriorly, a price-based power demand response model and a cooling and heating load demand response model that takes into account heating comfort ambiguity are established, and the demand response of cooling, heating and electricity load is constrained through users’ satisfaction. Subsequently, a low-carbon economic dispatching model of the CCHP microgrid with the minimum objective function of the operating total cost including electricity interactive cost, natural gas energy cost, renewable energy abandonment cost, carbon trading cost, power-to-gas operating cost and users’ compensation cost was established. It is solved by the adaptive differential evolution algorithm. In the end, we provide an toy example to illustrate the effectiveness of the proposed microgrid model.
