摘要/Abstract

摘要：

在过去30多年中，县域经济和城镇化的迅速发展促进了县域用电需求的快速增长。如何合理分析县域配电系统各方面的发展需求及其满足程度，对优化投资与改善规划决策进而实现可持续发展具有重要意义。在此背景下，运用马斯洛需求分层思想，首先提出了县域配电系统发展需求的层次划分方法，按照配电系统不满足发展需求时可能产生的负面影响，将配电系统发展需求划分为5个发展层次。此外，为便于对县域配电系统不同方面的发展需求进行量化评估，选取了5个基本发展需求指标作为表征发展需求特征的上层指标，并对由此得到的上层指标进行多维度分解得到下层的具体特征指标，上层指标和下层指标共同形成多层次发展需求特征指标集。之后，由下层指标评估结果综合得到上层5个基本发展需求指标值，并以该5个指标值作为表征县域配电系统不同方面发展需求的特征量，进而采用一种改进K均值聚类算法对多个县域配电系统进行聚类分析，得到县域配电系统的各大类典型发展需求特征。最后，采用河南省县域配电系统实际数据对所提方法进行了实证分析。

关键词: 县域配电系统, 发展需求, 马斯洛理论, 改进K均值聚类算法

Abstract:

The rapid developments of economics and urbanization of counties in the past three decades have led to the significant increases of power loads in many counties in China. The reasonable analysis on the various development demands and satisfaction degrees of county distribution systems has important significance to optimize the investment and improve the planning and decision-making, and then realize the sustainable development. On this background, with using Maslow demand hierarchy theory, we firstly propose the hierarchical division method for the development demand of county distribution system, and divide the development demand of distribution system into five development levels according to the probable negative impacts resulting from unfulfilled development demands. In addition, in order to facilitate the quantitative assessment on the different aspects of development needs of county distribution system, we choose five basic development demand indices as upper indices representing development demand characteristics, which are decomposed multi-dimensionally so as to acquire the sub-layer indices； and combine the indices in upper layers and sub-layers to obtain the multilevel characteristic index set. Then, the indices in the upper layer, which are calculated through the indices in the lower layers, are regarded as characteristic quantities to represent development demands in different aspects of the county distribution system and used for clustering analysis of multiple county distribution systems to obtain the typical characteristics of different categories based on improved K-means clustering algorithm. Finally, we adopt the actual data of county distribution systems in Henan province to demonstrate the proposed method.

Key words: county distribution system, development demand, Maslow's theory, improved K-means clustering algorithm
