摘要：
伴随“碳达峰、碳中和”行动方案的出台，投资推动供给侧结构调整和需求侧响应以实现双侧发力成为必然趋势，因此未来电网重点领域的投资策略和发展路径是电力企业所关注的重点。该文综合考虑电网投资的衍生价值，提出一种基于二项系数与变异系数的智能电网投资决策评价模型。首先，梳理电网投资衍生价值的概念、准则和方法；其次，从电网投资效益、电网运维成效、可持续发展价值3个方面构建智能电网投资衍生价值指标体系；并基于二项系数法和变异系数法构建主客观融合的组合赋权方法，根据不同场景需求来调整动态组合因子以实现多目标的动态平衡，体现主客观方法的优势互补；最后，北方某电网案例分析证明该文提出模型的合理性和有效性，并对北方某电网典型区域提出投资决策建议和精益化运维意见。

Abstract: With the introduction of the “Hit peak emissions and Carbon Neutrality” action plan, it has become an inevitable trend for investment to promote supply-side structural adjustment and demand-side response to achieve bilateral force. Therefore, the investment strategy and development path in key areas of the power grid in the future are determined by power companies. The focus of attention. This paper comprehensively considers the derivative value of grid investment, and proposes a smart grid investment decision-making evaluation model based on binomial coefficient and variant coefficient. First, sort out the concept, criteria and methods of grid investment derivative value; secondly, construct a smart grid investment derivative value indicator system from three aspects: grid investment benefit, grid operation and maintenance effectiveness, and sustainable development value; and based on the binomial coefficient method The combination weighting method of subjective and objective fusion is constructed with the coefficient of variation method, and the dynamic combination factor is adjusted according to the requirements of different demand scenarios to achieve the dynamic balance of multiple goals, reflecting the complementary advantages of subjective and objective methods; finally, a case analysis of a northern power grid proves This paper proposes the rationality and effectiveness of the model, and proposes investment decision-making suggestions and lean operation and maintenance suggestions for a typical area of a northern power grid.
