摘要
大规模风力发电并网引起的辅助服务成本已占到了一定比例。结合我国实际情况,分析大规模风电并网对电力系统辅助服务的主要影响要素,建立风电辅助服务成本的定量测算模型。以我国某省级电网为实际案例测算风电引起的调峰、调频和旋转备用辅助服务成本。案例分析表明,大规模风电并网将引起该省级电网辅助服务成本大幅上升,调峰成本占主要部分。
The ancillary cost is remarkably increased due to the large-scale wind power integration. The major impact factors of wind power on ancillary service cost are analyzed taking the actual situation in China into consideration. The ancillary service cost calculation model is established. Taking a provincial grid as exmaple, the costs of load regulation, frequency regulation and operational reserve are calculated. The case study shows that ancillary service costs, especially the load regulation cost, will increase rapidly with wind power ingeration.
