Abstract
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.
Highlights
According to the "Several Opinions on Further Deepening the Reform of the Electric Power System" (Zhongfa [2015] No 9) issued by the State Council of the Communist Party of China, the focus of the new round of power system reform is to orderly promote the reform of transmission and distribution prices [1]
Transmission and distribution prices are based on the principle of "permitted cost plus reasonable income" Accounting by voltage level, the supervision of transmission and distribution price will change the profit model of the regional distribution network, and the operating profit of the regional distribution network will be affected, affecting the investment capacity of the regional distribution network [2,3]
Assessing the investment capacity of the regional distribution network and judging whether the regional distribution network can meet future investment planning requirements is of great significance for the precise investment and development of the regional distribution network
Summary
According to the "Several Opinions on Further Deepening the Reform of the Electric Power System" (Zhongfa [2015] No 9) issued by the State Council of the Communist Party of China, the focus of the new round of power system reform is to orderly promote the reform of transmission and distribution prices [1]. Quantitative analysis of regional distribution network investment capacity refers to quantifying the net cash flow generated by regional distribution network power companies through operating activities and financing activities, and based on this investment capacity to analyze whether the power grid has the ability to meet future investment needs. This paper considers the impact of transmission and distribution price reforms, and combines key indicators such as electricity, electricity prices, and costs to build a quantitative model of grid investment capacity, and analyzes the grid's investment capacity based on the established quantitative model. For the construction of the key indicator system for the investment capacity of the regional distribution network, in addition to the conventional indicators such as electricity, electricity prices, and profits, this paper considers the original value of fixed assets, permitted costs, and permitted returns
