N2 - In this paper, the optimal operation method of electric-thermal coupling microgrid under the influence of many factors is studied. Firstly, the composition and structure of the electric-thermal coupling microgrid are introduced, and the models of various devices are established. Secondly, an objective function is established to minimize the daily operating cost of the microgrid, considering the demand response, the uncertainty, and the system constraints. Thirdly, considering that the constructed model is a mixed integer nonlinear programming problem, which is extremely difficult to solve, this paper uses the big-M method and piecewise linearization method to transform the model into a mixed integer linear programming problem. Finally, the impact of demand response, uncertainty and energy storage devices on microgrid is analyzed through a numerical example. The results show that considering demand response and energy storage devices can reduce the system operating cost. The uncertainty has a greater impact on the system operating cost, appropriate uncertainty parameters should be selected to make a trade-off between economy and security.
