发布时间：2018-08-26 08:12
【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 output is one of the key links in peak load regulation operation optimization of wind power system with large scale. In view of the actual characteristics of Chinese system operation, an interactive characteristic evaluation index considering the coupling relationship between wind power output and daily load time series is proposed, and a wind power output model based on peak-shaving problem is established. In this model, key scenarios, clustering scenarios and their probability distributions are used to characterize the comprehensive impact of wind power access on system operation and peak-shaving requirements. Based on the wind power output model, a peak shaving operation optimization model with large scale wind power system is established. Through the operation optimization under multiple scenarios, the expected values of each operation index are obtained, and the comprehensive analysis of the peak-shaving operation characteristics of the system is realized. An example of a province in western China is given to verify the effectiveness and practicability of the proposed method.
