摘　　要：灵活性资源是组成电力系统的新型设备,新能源渗透率增大不仅对功率及能量的需求产生影响,更对灵活性资源的短时响应能力产生需求。通过提取灵活性资源综合特征,分析电力系统对灵活性资源的主要需求,实现灵活性资源配置规划。该研究经区域电力系统电力电量平衡、新能源渗透率以及设备充裕度计算,得到能量、功率、持续放电时长、响应时长、单点规模限制等灵活性资源指标。对区域电力系统灵活性资源需求方案和配置方案的各特征指标赋值处理,采用TOPSIS算法衡量配置方案与需求方案的匹配程度,实现对灵活性资源配置方案的评估选择。Flexible resources are new types of equipment that form the power system,and the increase in the penetration rate of new energy not only has an impact on the demand for power and energy,but also has a demand for the short-term response ability of flexible resources.By extracting the comprehensive characteristics of flexible resources,the main demand of the power system for flexible resources is analyzed,and the flexible resource allocation planning is realized.In this study,the flexible resource indicators such as energy,power,continuous discharge time,response time,and single-point scale limit are obtained by calculating the power balance,new energy penetration rate and equipment adequacy of the regional power system.The TOPSIS algorithm is used to measure the matching degree between the allocation scheme and the demand scheme,so as to realize the evaluation and selection of the flexible resource allocation scheme.
