| 中文摘要: |
| 在输配电价改革背景的影响下，电网企业的盈利模式以及运营方式发生重大改变，亟需转换企业运营理念以及投资决策，为此建立了一种考虑输配电价改革的电网投资需求与投资能力协调优化模型，对电网投资决策提供方向。首先，对电网的投资需求方面进行分析，并将电网投资能力分为可分配利润、融资资金以及折旧费用，进而构建出基于输配电价改革下电网投资能力计算模型。然后，计算电网投资能力与投资需求的协调系数，考虑多约束条件建立电网投资需求与投资能力优化模型，并引入粒子群优化算法进行协调优化。最后，考虑投资需求与投资能力是否协调的情况进行仿真分析，依据仿真结果提出相应的投资经营策略。通过实例验证表明，该模型可以为电网企业制定合理投资计划提供较为有效的参考。 |

| Under the influence of the reform of transmission and distribution price, the profit model and operation mode of power grid enterprises have undergone major changes. It is urgent to transform the operation concept and investment decision of enterprises. The reformed power grid investment demand and investment capacity coordination optimization model provides a direction that can be optimized for power grid investment decision-making.Firstly, the investment demand of the power grid is analyzed, and the power grid investment capacity is devided into distributable profits, financing funds, and depreciation costs, and then a power grid investment capacity calculation model based on the transmission and distribution price reform is built. Then the coordination coefficient of power grid investment capacity and investment demand is calculated, considering multiple constraints, an optimization model of power grid investment demand and investment capacity is established, and particle swarm optimization algorithm is introduced for coordination optimization. Finally, simulation analysis is carried out considering whether the investment demand and investment ability are coordinated, and the corresponding investment management strategy is proposed according to the simulation results. The verification of the example shows that the model can provide a more effective reference for power grid enterprises to formulate a reasonable investment plan. |
