【摘要】：自从21世纪以来,我国通过开展针对可持续发展以及节能减排等相关技术的研究,来应对日趋严重的全球资源短缺及环境污染等问题。电力行业不仅承担着更多社会责任,同时也面临着严峻的挑战。其中,配电网是电力系统的重要组成部分,能够连接用户及发、输电系统,能够保证为电力用户提供高可靠性、高质量的电能供应。随着智能电网的发展,在经济型、适应性、可靠性等方面对配电网规划方案进行综合评价能够检验当下配电网是否符合智能电网的相关要求。本文从电网利益相关者需求的角度,构建基于不同层次需求的综合评价指标体系,其中包括宏观评价指标集和微观评价指标集,该指标体系能够从多个角度反应出配电网规划的发展水平和运行过程中的薄弱环节。本文提出两种指标权重计算模型,分别为基于熵权法和ANP法的宏观指标权重计算模型和基于灰色关联度法的微观指标权重计算模型,通过该模型计算各个指标权重值,能够综合主观和客观信息,从而对评估结果起到优化作用。通过德尔菲法,获得微观评价指标值和评价值之间的关系,得到指标评分方法,结合基础数据和计算出的指标权重值,最终得出配电网规划方案综合评价结果。通过对实际案例进行计算分析,本文验证所构建的配电网规划方案综合评价体系可以较为全面地体现配电网规划的发展水平,并能够帮助发现目前配电网的薄弱环节,进而对配电网的智能化发展进行指导并提出合理建议。在我国当前智能电网环境下,本文基于配电网规划的利益需求和核心价值,通过构建全面、合理的综合评价指标体系,对指标权重计算模型和评价方法进行研究,不仅使该评价体系具有实际操作性,而且符合了智能电网的相关要求。
[Abstract]:Since 21th century, China has carried out research on sustainable development, energy saving and emission reduction and other related technologies to deal with the increasingly serious global shortage of resources and environmental pollution. At the same time, distribution network is an important part of power system. It can connect users and transmission systems, and can provide high reliability for power users. High quality power supply. With the development of smart grid, in economy, adaptability, The comprehensive evaluation of the distribution network planning scheme from the aspects of reliability and other aspects can test whether the current distribution network meets the relevant requirements of the smart grid. Constructing a comprehensive evaluation index system based on different levels of needs, including macro evaluation index set and micro evaluation index set, The index system can reflect the development level of distribution network planning and the weak link in the operation process from many angles. The calculation model of macroscopic index weight based on entropy weight method and ANP method and micro index weight calculation model based on grey correlation degree method are used to calculate each index weight value, which can synthesize subjective and objective information. Through Delphi method, the relationship between the micro-evaluation index value and the evaluation value is obtained, and the index scoring method is obtained, which combines the basic data and the calculated index weight value. Finally, the comprehensive evaluation results of distribution network planning scheme are obtained. Through the calculation and analysis of actual cases, this paper verifies that the comprehensive evaluation system of distribution network planning scheme can fully reflect the development level of distribution network planning. And it can help to find the weak links of distribution network, and then guide the intelligent development of distribution network and put forward reasonable suggestions. In the current smart grid environment of our country, this paper is based on the benefit demand and core value of distribution network planning. By constructing a comprehensive and reasonable comprehensive evaluation index system, the calculation model and evaluation method of index weight are studied, which not only makes the evaluation system practical, but also meets the requirements of smart grid.
