    摘要:

    对源荷双侧存在的不确定性进行精细化建模,可提升广域源荷协调调度结果的有效性。分别以风电功率和分时电价为不确定变量,利用历史数据构建基于Wasserstein距离的概率分布模糊集来表征风电功率和分时电价的不确定性,并根据各类民用负荷特性建立分时电价引导下广域分布的民用负荷需求响应不确定模型。建立基于Wasserstein距离的广域源-荷协调双层分布式鲁棒优化调度模型,优化求解得到火电机组、风电场和各类广域民用负荷的调度计划。最后通过算例仿真验证所提方法可有效挖掘广域民用负荷调峰潜力,降低系统运行成本,提高风电消纳能力,平衡调度计划的经济性和鲁棒性。

    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.
