【摘要】：西北地区可再生能源资源与电力需求不平衡的现状,使得发展风火联合外送成为促进新能源消纳的重要举措。而风电出力的不确定性给风火联合外送的经济性、可靠性效益评估造成了困难。针对该问题,文章采用风电多状态模型,引入机组剩余容量的概念,提出了联合外送概率模型以模拟送端电网对受端电网的电力支援过程。结合各类型电源特点,设计了考虑风火联合外送的互联系统随机生产模拟算法框架。通过EPRI 36算例验证了所提方法的有效性,并且通过对酒泉—湖南±800 k V直流输电工程进行随机生产模拟,研究了酒泉直流对受端电网充裕度的改善、酒泉直流的环保效益以及直流输电利用小时数对酒泉直流经济性的影响。
[Abstract]:Due to the imbalance between renewable energy resources and power demand in Northwest China, the development of wind and fire combined outputting has become an important measure to promote the absorption of new energy. The uncertainty of wind power supply makes it difficult to evaluate the economic and reliability benefits of combined wind and fire delivery. In order to solve this problem, this paper adopts wind power multi-state model, introduces the concept of unit residual capacity, and presents a joint outputting probability model to simulate the power support process of the receiving network. Considering the characteristics of various types of power supply, an algorithm framework for stochastic production simulation of interconnected systems considering wind and fire combined outputting is designed. The effectiveness of the proposed method is verified by an example of EPRI 36, and the improvement of the adequacy of Jiuquan DC to the receiving power network is studied by the random production simulation of Jiuquan-Hunan 卤800kV HVDC transmission project. The environmental benefit of Jiuquan DC and the influence of the number of hours of HVDC utilization on the DC economy of Jiuquan.
