基于模糊理论的数字电网发展指数评估

Evaluation of Digital Power Grid Development Index Based on Fuzzy Theory

  • 摘要:
      目的  数字电网是一个全新概念,是新型电力系统的最佳承载方式。在数字化转型中,电网企业都致力于建设数字电网。数字电网有别于传统智能电网,需要从宏观上衡量其发展水平。因此,有必要构建全新的数字电网综合指数以指导电网企业开展数字电网建设,并分析建设中存在的不足。
      方法  基于对数字电网发展指数关键构成因素的分析,建立了数字电网指数评估体系,针对性选择数字电网的核心指标。首先对各级关键指标赋权,然后基于模糊理论构建了数字电网发展指数模型。
      结果  选取了南方电网下属的三家电网公司进行了实例分析,分析结果表明:数字电网发展指数总体不高,除了本体安全指标外,其他方面均有广阔的发展空间。
      结论  基于该方法能有效测算出电网企业数字电网发展状态,以及未来的发展趋势。

     

    Abstract:
      Introduction  Digital power grid is a brand new concept and the best bearing mode of new power system. In the digital transformation, power grid enterprises are committed to constucting a digital power grid. Digital power grid is different from traditional smart power grid. It is necessary to measure the development level of digital power grid from a macro perspective. Therefore, it is necessary to build a new digital power grid comprehensive index to guide power grid enterprises to construct the digital power grid, and analyze the shortcomings in the construction.
      Method  Based on the analysis of the key components of digital power grid development index, a digital power grid index evaluation system was established to select the core indicators of digital power grid. First, the key indicators at all levels were weighted, and then a digital power grid development index model was constructed based on fuzzy theory.
      Result  Three power grid companies subordinate to China Southern Power Grid are selected for case study. The analysis results show that the overall development index of digital power grid is not high, and there is broad development space in various fields other than ontology security index.
      Conclusion  Based on this method, the development status and future development trend of digital power grid of power grid enterprises can be effectively estimated.
