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.
