摘要
风电具有随机性和间歇性,其不确定性增加了系统运行的风险,也增加了辅助服务的需求。为保证风电并网后系统运行的可靠性,需在原来运行方式的基础上,安排一定容量的旋转备用以响应风电场发电功率的随机波动,以维持电力系统的功率平衡与稳定。本文考虑了系统的负荷预测偏差和风电功率预测偏差,对并入风电前后系统的备用情况差异性进行分析,为电力系统安全稳定运行提供参考意见。
The randomness and intermittency of wind power increases the risk of operating system,and increases demand of ancillary service.To guarantee reliability of operating system after integration of wind power,extra spinning reserved capacity will be needed based on former operating mode which is in order to response random fluctuation of wind farms′s generation power then maintain power system′s power balance and stability.The load forecast and wind forecast of the system are considered in this paper to analyze...
