摘　　要：随着风电并网容量的增加,调峰和电网输送能力已成为电力系统消纳风电的瓶颈。为直观表达省级系统消纳风电的能力,指导风电发展规划以及未来调度运行工作,结合中国电力系统运行特性,研究了综合考虑调峰约束和电网输送能力约束的风电电量消纳预测方法,并根据中国北方风电富集省份现有的电网条件、电源结构、实际运行方式等信息,对多种场景下两相邻省份水平年风电电量消纳情况进行了详细预测分析,最后根据电力系统实际运行情况,提出了提高风电消纳能力的措施和建议。With the increasing of wind power installed capacity,peak load regulation and transmission capacity have become main restrictions for accommodation of wind power.In order to provide an intuitive demonstration on the accommodation of wind power and guidance for the planning and dispatching of wind power,this paper presents a method for predicting the accommodation of wind energy considering peak load and transmission regulation.Based on the present condition of the gird,construction of power source and the actual operational data of the northern provinces of China with rich wind power resource,this paper analyzes and predicts two provinces＇ available capability of wind energy in the target year under different scenarios.At last,this paper gives advices to improve the capability to connect wind power.
