Abstract:In order to improve the effectiveness of the results of the wide area source-load scheduling, the uncertainty of both sides of source load was be modeled.Wind power and time-of-use (TOU )price were taken as uncertain variables respectively, and the historical data were used to construct the fuzzy set of probability distribution based on Wasserstein distance to characterize the uncertainties of wind power and TOU price, and the uncertain model of wide area civil load demand response guided by TOU price was established according to the characteristics of various civil loads. Based on Wasserstein distance, a wide area source-load coordination two-level distributionally robust scheduling model was established, and the scheduling plans of thermal power units, wind farms and all kinds of wide-area civil loads were optimized and solved. Finally, an example is given to verify that the proposed method can effectively tap the peak load potential of wide area civil load, reduce the operating cost of the system, improve the wind power consumption capacity, and balance the economy and robustness of the scheduling plan.
