基于规划项目属性分类的配电网精确投资策略研究

Research on Accurate Investment Strategy of Distribution Network Based on Attribute Classification of Projects

城市配电网是电网的重要组成部分,直接面向终端用户,与广大人民群众的生产生活息息相关,是服务民生的重要基础设施,《国务院关于加强城市基础设施建设的意见》中明确提出要进一步加强城市配电网建设。配电网投资逐年递增,针对目前存在的资金难以合理分配、投资均衡性差以及配网项目缺乏明确的评价和比选标准等问题,提出了基于规划项目属性分类的配电网投资分配及项目优选实用方法。基于实际工程,确定了规划项目的优选排序原则,提出了排序模型;综合考虑该评价体系所得的项目群,提出了评价指标体系的优化方法;以投资分配比例为约束,确定了配电网的项目优选结果;实例分析结果验证了研究成果的有效性。

Distribution network is an important part of power grid,directly facing the terminal user and closely related to daily production and livelihood,State council on strengthening the city infrastructure construction opinions clearly put forward to further strengthen the city distribution network construction.Distribution network investment increased year by year,according to the existing funds to reasonable allocation,investment equilibrium and distribution project evaluation and selection of the lack of clear standards,put forward the attribute classification of distribution network planning project investment allocation and optimization method based on the practical projects.Based on the actual project,determine the preferred ordering principles of project planning,proposes a ranking model;considering the evaluation system of the project group,put forward the optimization method of evaluation index system;investment allocation ratio as constraints,determine the results of optimization of distribution network project;case analysis results verify the effectiveness of the research results.
