Research on the Calculating Model of Power Grid Investment Ability under the Reform of Transmission and Distribution Price

The reform of transmission and distribution prices requires grid companies to strengthen input and output efficiency and optimize resource allocation. This paper establishes a mathematical model that controls the upper limit of the investment scale based on the transmission and distribution price, and calculates the investment capacity of the power grid based on the asset-liability ratio target. Case verification shows that using this model, power grid companies can objectively evaluate their own maximum investment capabilities, and provide a scientific basis for power grid companies to formulate reasonable investment plans, at the same time, it also provides a reference for other companies to calculate their investment capacity under the limitation of debt ratio.
