摘　　要：建立了基于蒙特卡罗仿真的含风电场的发输电系统可靠性分析模型,该模型不仅考虑了风速的随机性、风电机组强迫停运率及其与气候的相关性,而且计及了输电网络故障率和输电线路有功功率限制。将该模型应用于含风电场的电力系统仿真,按照在满足系统安全约束条件的前提下充分利用风电的原则,对系统进行模拟调度,计算出能反映风电价值的可靠性指标,为风电场的规划与运行提供了重要的参考价值。This paper introduces a reliability assessment model of wind power integration in power systems based on the Monte-Carlo simulation approach, which considers not only the randomicity of the wind, weather effect on wind power generation forced outage rate, but also the transmission network failure rate and capability constraints. This model is applied to simulate power system including wind power generation. Power system is dispatched in term of the principle that wind power is employed sufficiently, according to meeting system security constraints. The reliability index is calculated and will provide the valuable reference for wind farm operation and planning.
