摘要:

为切实降低用户办电成本,电网投资界面被要求延伸至用户红线,而其延伸成本如何在政府、电网、用户多主体间分配尚缺乏统一合理的标准。基于此,首先阐述电网投资界面延伸情况及投资主体利益诉求,并对电网接入工程投资成本进行分析;其次,以最大化各主体投资比例与其最不理想比例差距为目标,构建Nash-Harsanyi讨价还价博弈模型,通过初始投资比例、风险分担比例、合作协同能力量化谈判力水平,为电力接入费用寻求公平合理的政企共担投资策略;最后,以某经济开发区电网接入工程为例进行算例分析,结果表明,电网、用户、政府投资比例由0.65∶0.14∶0.21优化为0.61∶0.12∶0.27,三者满意度均得以提升,其中电网企业由于较高的谈判力得到最大程度提升,这有助于推动电网投资界面延伸工作,进一步优化营商环境。

Abstract:

In order to effectively reduce the cost of power supply for users, the grid investment interface is required to extend to the user's red line. However, there is no uniform and reasonable standard on how to allocate the extension cost among the government, power grid enterprises and users. This paper firstly expounds the extension of the power grid investment interface and the interest demands of investment entities, and analyzes the investment cost of power access project. Secondly, aiming at maximizing the gap between the investment proportion of each entity and its least ideal proportion, the Nash-Harsanyi bargaining game model is constructed. The bargaining power is quantified through the initial investment proportion, risk sharing ratio and cooperation ability, so as to seek a fair and reasonable government-enterprise sharing strategy for power access costs. Finally, a study is conducted for a power access project in an economic development zone. The results show that the investment proportion among power grid enterprise, users, and government has been optimized from 0.65∶0.14∶0.21 to 0.61∶0.12∶0.27, and the satisfaction degree of all three entities has been improved. The satisfaction degree of power grid enterprise has been greatly improved due to its high bargaining power, which is helpful to promote the extension of the investment interface and further optimize the business environment.
