摘要:The transmission and distribution price reform has changed the profit model of the power grid, and a reasonable assessment of the investment capacity of the regional power grid is critical to the future investment planning of the power grid. To this end, first of all, sort out the key index system of power grid investment capacity for transmission and distribution price reform. Then comprehensively consider the available distribution profit, depreciation and external financing of the power grid, and establish a quantitative model of power grid investment capacity; Finally, the ability to invest in the establishment of quantitative models to measure the ability of a power grid investment companies, investment capacity is calculated after the reform of the electricity transmission and distribution, in order to verify the ability to quantify the investment rationality and effectiveness of the model. Finally, taking three power companies as examples, the feasibility of the model and the rationality of investment capacity evaluation are verified.
