摘要 天山-中州±800kV特高压直流输电工程(简称天中直流)是“疆电外送”首个特高压直流项目。天中直流工程设计年输送电量440亿kW·h.对实现西电东送、促进更大范围的能源资源优化配置发挥了重要作用。天中直流为风火打捆输送,风火打捆比例不同会对河南电网运行带来不同程度的影响。新疆电网低谷时段的送电电力大小将直接影响河南电网的调峰运行,并增加河南电网的调峰运行费用。以此工程为例,进行了基于大比例新能源输电的受端电网调峰费用测算及补偿机制研究.以期为相关电价政策制定提供参考。 Tianshan-Zhongzhou UHVDC Project is the first UHVDC project in Xinjiang for outbound power transmission. With a designed annual transmission capacity of 44 billion kW·h, it will play an important role in energy resources optimization for a large area. The Tianshan-Zhongzhou UHVDC Transmission Project is built for transmission of both thermal and wind power in Xinjiang, Different proportion of the thermal and wind power has different influences on the operation of Henan power grid. The magnitude of power transmission during Xinjiang power valley will influence the load peaking operation and increase the peaking cost of Henan power grid. By taking this project as an example, a study is made on estimation of receiving-end grid power peaking cost and compensation mechanism based on large-proportion renewable energy transmission, which is expected to provide a reference for formulating relevant electricity price policy.
