考虑投资均衡和效益性的中压配电网投资分配

针对目前配电网投资缺乏合理的分配方法，提出适用于中压配电网多地区和多类项目投资分配模型。首先从投资需求、区域电力需求、问题现状和规划目标、投资效益、项目管理水平和风险分担能力等维度分别梳理提炼中压配电网投资分配评价指标和评分方法，引入面板回归分析，建立地市供电公司各地区中压配电网投资与指标综合评分的函数关系。其次基于多目标优化决策技术，分别以投资均衡和整体效益、单位投资效益最优为目标，提出增供电量、提升供电可靠性和降损效益等大类项目和各功能项目的投资分配模型。实证分析表明：所提模型可为地市供电公司中压配电网各地区和各类项目投资分配提供支撑。

Investment Allocation for Medium-Voltage Distribution Networks Considering Investment Equilibrium and Benefits

In view of the lack of reasonable investment allocation methods for distribution networks, this paper proposes an investment allocation model for multi-region and multi-type projects of medium-voltage distribution networks. Firstly, from the perspective of investment demand, regional power demand, problem status and planning targets, investment benefits, project management level, risk-sharing ability and other factors, the indicators and grading methods are investigated and determined for investment allocation of the medium-voltage distribution networks, and the panel regression analysis is introduced to establish the functional relationship between the medium-voltage distribution network investment of each prefecture-level power supply company and the integrated indicator grading. Secondly, based on the multi-objective optimization decision-making techniques, and with the objective of investment balance and overall benefits and the best unit investment benefits, an investment allocation model is proposed for various large-scale projects and various function projects to increase power supply, improve power supply reliability and reduce line losses. The case study shows that the proposed model can provide a support for the investment allocation for various regions and various projects of the medium-voltage distribution networks of prefecture-level power supply companies.
