摘要
由于在资源分布、风电接入模式、电源构成、电网结构等方面的特异性,我国不能照搬欧美等风电发达国家的运行经验,必须构建符合自身特点的电力平衡优化技术体系。从分析大规模风电的基本特性出发,归纳了针对风电波动性与不确定性的风电主要建模方法。将我国风-火-水互济系统的有功平衡问题划分为中长期/短期机组组合计划、日内滚动计划和实时频率调节等若干子问题研究,分析了各子问题的研究现状与技术瓶颈,对研究、设计含大规模风电接入的电力系统多时间尺度的有功平衡技术体系有参考意义。
Owing to China＇s special features in resources distribution, wind power on-grid mode, power composition and power grid structure, China shouldn＇t simply draw on experience from developed countries like Europe and America. China should establish our own optimized power balance technology system in accordance with its own characteristics. Through analyzing the inherent characteristics of large-scale wind power, the main modeling methods for the fluctuation and uncertainty of wind power are concluded in this paper. The active power balance problems in the wind-coal-hydro mixed power grid are divided into several sub-problems： mid- and long-term and short-term unit commitment plan, rolling scheduling within one single day, real-time dispatching and so on. Finally, the research status and technical bottlenecks of those sub-problems are analyzed, respectively. The results have reference significance to the study and design of active power balance technology for the multi-time scale power system with large-scale wind power integration.
