| 摘 要： | 随机性风电出力的准确建模是含大规模风电系统调峰运行优化的关键环节之一。针对中国系统运行的实际特点,提出计及风电出力与日负荷时序耦合关系的交互特性评价指标,并据此建立基于调峰问题驱动的风电出力模型。该模型以关键场景、聚类场景及其概率分布表征风电接入对系统运行和调峰需求的综合影响。基于该风电出力模型,建立了含大规模风电系统的调峰运行优化模型。通过多场景下的运行优化,获得各项运行指标的期望值,实现对系统调峰运行特性的综合分析。对中国西部某省进行了算例分析,验证了所提方法的有效性和实用性。

| Abstract: | Accurate modeling of stochastic wind power is one of the key links for peak load regulating operation and optimization in systems with large-scale wind power. According to the actual operation characteristics in China''s power systems, the interactive characteristic indices considering the coupling between wind power and load are proposed, and a wind power output model based on peak load regulation problems is put forward. This model uses key and clustering scenarios to characterize the influence of wind power on the power system operation and peak demand. Afterwards, an operation optimization model for peak load regulation with large-scale wind power based on the wind power output model is established. The expected value of various operation indices through operation optimization in multiple scenarios is obtained, and the analysis on peak load regulating operation characteristics is comprehensively accomplished. A case analysis is made on a province in West China that verified the validity and practicality of the proposed method. |
