the flexible operation of carbon capture power plant (CCPP) makes it possible for quick-adjusting of output of CCPP. This advantage of CCPP can be used to alleviate the wind power output by combining operation of CCPP and wind farm and reduce the impact of wind power fluctuations on the power system. In this paper, the minimized fluctuation of wind power output alleviated by CCPP,the lowest operating cost of thermal power plants and the lowest carbon trading cost are taken as the objectives, so the model can take economic, environmental and safety benefits into account. The built model is solved by MPSO and using chaos searching to reduce the influence of total output of CCPP on alleviating the fluctuation of wind power and by changing weight coefficient of transformation matrix parameters can achieve the flexible adjustment of dispatch model. The feasibility and effectiveness of the proposed model are validated by case study..
