The use of new energy is receiving more attention．Wind energy as a kind of clean，abundant reserves renewable energy is the most important energy of new energy source. Due to the randomness of wind energy, the use of wind power will increase the uncertain factors of the power system dispatching, and new demands of the economic dispatching of the power system should be raised. According to the characteristics of economic dispatching of thermal plants and wind power, and established economic dispatching model of power system include wind power. The mixed integer programming approach theory is used, which aims to solve the problems between the wind power units and thermal units. Examples indicate that the combination of wind and thermal power will reduce the fuel cost of the running system, the conventional units’ status of on and off and their outputs are also affected. In this article, the clean and renewable characteristics of wind power is fully used, reduced the thermal units’ status of on and off. It can achieve emissions-r
