摘要
风电容量可信度评估对于风电资源的发展和电力系统扩展规划具有重要的指导意义。采用随机生产模拟技术,分析比较了基于失负荷期望(LOLE)和电量不足期望(EUE)等容量充裕度指标的风电容量可信度。理论分析和算例仿真表明,LOLE指标和EUE指标随负荷变化曲线的差异,导致了基于LOLE指标和EUE指标的风电容量可信度存在明显的差异。
Estimation of wind power capacity credit plays an important role for development of wind power resources and expansion planning of power systems.Using the probabilistic production simulation technology,wind power capacity credits based on the capacity adequacy indexes LOLE and EUE are analyzed and compared.Theoretical analysis and numerical simulation show that the difference variation of the EUE index and LOLE index with load leads to significant difference in the EUE-based and the LOLE-based wind power capacity credits.
