大规模风电入网辅助服务成本补偿机制研究

Compensation Mechanism for Ancillary Service Cost of Grid-Integration of Large-Scale Wind Farms

随着大规模的风电快速发展,电力系统的辅助服务需求会越来越多。辅助服务问题已经成为制约大规模风电并网的最重要因素之一。量化研究了大规模风电接入对电力系统辅助服务成本的影响,其主要来自调峰及备用。依此为基础,从中国电力改革与发展的角度,提出了几种因风电接入导致的辅助服务成本的分摊与补偿机制,按可行性难易程度提出了相应的政策建议。

With the rapid development of large-scale wind farms in China, there will be more and more demand on ancillary services in power sector, so the ancillary service is becoming one of the most important factors restricting the grid-integration of large-scale wind farms. The impacts of grid-integration of large-scale wind farms on power grid ancillary service costs, which are mainly caused by the peak-load regulation and reserve capacity, are researched quantitatively. On this basis, in the viewpoint of reformation and development of China＇s power sector several mechanisms of apportionment and compensation of ancillary service costs due to the grid-integration of large-scale wind farms are proposed, and corresponding policy suggestions are recommended according to the difficulty levels of feasibilities.
