摘要/Abstract

摘要： 近年来，电网公司持续投入巨大资金加快配电网建设和改造，配电网投资总体逐年递增。面对巨大的投资规模，配电网投资效率成为电网公司重点关注的问题。针对省级电网公司配电网资金难以合理分配、地市级电网公司之间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，提出了配电网投资分配及项目优选的实用化方法。基于配网运行状态影响因素分析，构建了同时适用于项目群评价和单项目评价的配电网运行状态改善效果综合评价体系；综合考虑该评价体系所得的项目群评价结果以及配电网供电水平、规模、运行水平和盈利能力等因素，建立了可用于省级电网公司资金分配的配电网投资分配模型，以计算出地市级电网公司的投资分配比例；以投资分配比例为约束，利用单项目评价结果和项目投资额所得的项目综合排序，确定出地市级电网公司的项目优选结果；实例分析结果验证了研究成果的有效性。

Abstract: With fast development of distribution network, there are several problems appeared, including fund allocation difficulty in provincial power grid, investment imbalance in city power grid, lack of clear evaluation and selection criteria for distribution projects. A practical method of distribution network investment allocation and project selection optimization method is proposed. Firstly, an operating status improvement assessment system for project group and single project basing is built based on analysis of influencing factors. Secondly, an investment allocation model for funds allocation of provincial power grid company is proposed, considering the project group evaluation results, as well as distribution network level, scale, operation level and profitability, in order to calculate investment allocation ratio of municipal power grid companies. Then, with constraints of investment limits for municipal power grid companies, projects optimal selection is performed based on the sorting of single-project evaluation and project investment results. The case study results demonstrated the effectiveness of proposed method.
