摘要

提出一种考虑柔性资源协同互动的配电网灵活性评估方法.首先,构建包含协同调节能力、协作效益质量和电网可靠性三方面的灵活性评估指标体系;其次,采用高斯混合模型构建了典型运行场景,采用层次分析法和随机森林模型分别确定评估指标的主观权重与客观权重,并通过双层评估流程,计算得到各典型场景下的评估指标值;然后,根据典型场景的出现概率,加权得到各个柔性资源接入方案的综合灵活性评估指标值;最后,通过54 节点配电网算例分析,验证了所提方法的可行性和有效性.

Abstract

A distribution network flexibility evaluation method considering collaborative interaction of flexible resources is proposed.Firstly,a flexibility evaluation indicator system is constructed,which includes three aspects:collaborative regulation capacity,collaborative efficiency quality,and power grid reliability.Secondly,a Gaussian mixture model is used to construct typical operating scenarios,and the subjective and objective weights of evaluation indicators are determined using Analytic Hierarchy Process and Random Forest Model,respectively.Through a double-layer evaluation process,the evaluation indicator values for each typical scenario are calculated.Then,based on the probability of typical scenarios appearing,the comprehensive flexibility evaluation index values of each flexible resource access scheme are weighted.Finally,the feasibility and effectiveness of the proposed method are verified through the case study on a 54-bus distribution network.
