摘　　要：在新型电力系统发展的背景下,针对配电网规划建设和配电网关键技术在实际应用时与所处时空的适应能力、应用缺陷难定量化等问题,分析新型配电网关键技术的建设条件,提出一种基于电网满足度、时空资源度、成效改善度的三维立体空间的技术时空适应性评估模型.采用连续区间有序加权平均算子对层次分析法主观赋权进行改进,引入标准间冲突性相关性法构建的主客观组合赋权方法,解决了单一赋权法具有偏向性的问题.利用模糊综合评价法确定各指标隶属度,进而得到新型配电网关键技术评价等级.算例结果表明,所提方法能够量化配电网关键技术与所处时空的契合程度和双向辨识关键技术对于不同时空的适应性以及不同时空对于技术应用的满足度,揭示配电网关键技术的薄弱环节,有助于提升配电网投资效率与效益,更好地服务经济社会高质量发展.In the context of the development of new power systems,a three-dimensional spatio-temporal adaptation assessment model based on grid satisfaction,spatio-temporal resources,and effectiveness improvement is proposed to address the problems of distribution network planning and construction,the adaptability of key distribution network technologies to the space and time in which they are applied,and the difficulty of quantifying application defects.Subjective assignment in hierarchical analysis is improved using continuous interval ordered weighted average operator,and the problem of bias of the single assignment method is solved by the introduction of a subjective-objective combination assignment method constructed by the conflicting correlation among criteria method.The degree of affiliation of each indicator is determined using the fuzzy integrated evaluation method and the evaluation level is then obtained.The case studies show that the proposed method can quantify the degree of fit between the key technologies of the distribution network and the space-time,identify the adaptability of the key technologies to different space-times and the degree of satisfaction of the application of the technologies in different space-times,and reveal the weaknesses of the key technologies of the distribution network,which can help improve the efficiency and effectiveness of the investment in the distribution network and better serve the high-quality development of the economy and society.
