For dealing with such issues as slow response of unit adjustment and big planning and tracking error due to uncertainty of wind power

in this paper

an ultra-short term dispatching method with MPC idea is introduced. For accepting the wind power as much as possible

such two kinds of rolling optimization models as complete acceptance of wind power and minimum wind power curtailment is set up based onMPC basic principle and with real time output of the unit as ultra-short term prediction data as feedback information

the appropriate model is selected and optimized as per the different situations together with criteria so to achieve maximum acceptance of wind power and weaken the influence of uncertainty factor to thesystem during the tracking optimal dispatching proposal. The certain grid in Jilin is taken as an exampleand effectiveness of the proposed model and algorithm is verified by the calculation analysis.
