【摘要】：为实现配电网的精细化管理与评价,提出了网格化中低压智能配电网评价指标体系及综合评价方法。首先定义了中低压智能配电网网格以及台区单元的划分原则,并在此基础上从电力用户和电网企业2个利益相关者的角度进行分析,结合各自的需求及其关注的指标类型,构建了对配电台区单元和10 k V主干网格的配电网精细化评价指标体系。同时,提出了可实现多目标决策的基于最小二乘法和灰色关联度法的综合评价方法,该方法应用最小二乘模型优化了由环比评分法确定的主观权重和由熵权法确定的客观权重,兼顾了评价指标的主客观信息。将该评价指标体系及评价方法运用于区域配电网算例,得出被评价区域配电网各网格的优劣排序及各网格内的薄弱环节。结果表明,该指标体系及评价方法可以为智能配电网的建设和改善运行提供依据,从而服务于智能配电网的精细化管理。
[Abstract]:In order to realize the fine management and evaluation of distribution network, the evaluation index system and comprehensive evaluation method of grid medium and low voltage smart distribution network are put forward. Firstly, the paper defines the dividing principle of grid and unit of medium and low voltage smart distribution network. Based on this, the paper analyzes the grid of medium and low voltage smart distribution network from the perspective of two stakeholders of power users and power grid enterprises, and combines their needs and their concerned index types. A fine evaluation index system of distribution network for distribution station area unit and 10 kV backbone grid is constructed. At the same time, a comprehensive evaluation method based on least square method and grey correlation method is proposed, which can realize multi-objective decision making. Using least square model, the subjective weight determined by loop scoring method and the objective weight determined by entropy weight method are optimized. The subjective and objective information of the evaluation index is taken into account. The evaluation index system and evaluation method are applied to the example of regional distribution network, and the order of each grid and the weak links in each grid are obtained. The results show that the index system and the evaluation method can provide the basis for the construction and improvement of the smart distribution network, so as to serve the fine management of the smart distribution network.
