Under the background of low carbon electricity, a dispatching model of CHP system containing wind power is proposed, which can consider both of the economy and low carbon of electric power production. The electric boiler is installed on the power generation side to decoupling thermoelectric coupling constraints, and the flexible load is scheduled on demand side to achieve load shaving. The minimum cost of system power generation is the goal of economic optimization, and the minimum cost of carbon trading is the goal of low-carbon optimization. Fuzzy bi-objective optimization model is proposed to transform the multi-objective problem into single-objective problem, and the ICA is used to solve the model. Through simulation examples in different scenes shows that the proposed model and algorithm are effective and superior.
