Research on power grid investment decision model based on constraints of key factors of transmission and distribution price

With the promulgation of the notice of market-oriented reform of coal-fired power generation, the reform of transmission and distribution electricity price has entered a substantive reform stage. General industry and Commerce have all entered the market, the proportion of electricity marketization has increased significantly, and the profit space of power grid companies has been further narrowed. Facing the dual pressure of performance assessment of state-owned assets management commission and verification of transmission and distribution electricity price, investment, as an important driver of business growth, the scientific value of its front-end decision-making has an important impact on stabilizing transmission and distribution electricity price and improving the company's business performance. However, the current investment plan arrangement of front-end infrastructure projects is not effectively connected with the key elements of transmission and distribution electricity price verification, and there is still great uncertainty about the supporting role of transmission and distribution electricity price. There is a lack of overall arrangement in advance, which is not conducive to improving the company's operating performance. Therefore, this paper excavates the investment and asset formation laws of infrastructure projects, makes the linkage relationship between investment, asset formation rate, transmission and distribution price and business performance smoother, studies and builds a power grid investment decision-making model based on the constraints of key elements of transmission and distribution price, provides quantitative reference for investment arrangement, and improves the scientific value and rationality of investment arrangement at the source.
