摘　　要：针对新型配电系统内灵活性资源接入规模逐渐扩大,过往配电网灵活性评估方法难以适应配电系统发展状况的问题,提出了基于云模型的新型配电系统灵活性评估方法。首先通过影响系统灵活性的数个指标构建了配电网灵活性评价体系;其次采用了主客观结合的层次分析法(analytic hierarchy process,AHP)-熵权法对构建的灵活性评价体系进行赋权;最后针对系统灵活性状态难以直观描述、现有灵活性评估方法难以完整表征系统灵活性状态的问题,提出了基于云模型的配电系统灵活性评估方法,并通过我国某地区配电系统运行实测数据进行了仿真验证。A new distribution system flexibility evaluation based on cloud models is proposed to address the issue of the gradual expansion of the scale of flexible resource access into the new distribution system,making it difficult for the previous distribution network flexibility evaluation methods to adapt to the development status of the distribution system.Firstly,a distribution network flexibility evaluation system was constructed based on several indicators that affect the system flexibility;Secondly,the AHP entropy weight method,which combines the subjective and objective factors,was used to weight the constructed flexibility evaluation system;Finally,to address the issues of the difficulties in intuitively describing the flexibility status of the system and in fully characterizing the flexibility status of the system using the existing flexibility evaluation methods,a cloud model-based distribution system flexibility evaluation method was proposed.Simulation verification is conducted using the actual data from a distribution system operation in a certain region of China.
