Abstract
In order to deal with the severe external supervision and challenges, and improve the scientific rationality of internal investment structure decision-making, this study explored the idea of voltage level investment structure decision-making considering the power grid development and operation benefits. Firstly, based on the study of the relationship between historical investment scale and power grid indicators, the investment demand of power grid is determined; secondly, the influence path of investment on business efficiency is sorted out, and the differences of investment, capital transfer and depreciation of different voltage levels are studied and determined, and the operation benefit level of the company under different investment schemes is calculated. Finally, the index system of investment structure optimization is constructed to quantify the power grid and benefit status of the company under different investment structures, so as to optimize the company’s investment scheme and promote the high-quality development of the company and power grid.
Highlights
Under the new energy security strategy of "four revolutions and one cooperation", the reform of power transmission and distribution price, the reform of electricity selling side market and the energy transformation have been promoted in depth
How to consider the impact on the overall performance of the company at the same time in the investment decisionmaking is imminent; in addition, the company's investment scale and investment structure decisionmaking mainly rely on experience decision-making, lack of scientific and objective quantitative basis, it is difficult to effectively link up external supervision, internal performance objectives and Business needs, it is urgent to build investment scale and structure calculation model to support scientific, efficient, intelligent and accurate investment decision-making
Starting from the current situation and management objectives of power grid, this paper studies the relationship between historical investment and current situation of power grid, and determines the investment demand of different voltage levels
Summary
This paper studies the relationship between the historical investment and the current situation of the power grid from the current situation and management objectives of the power grid, and determines the investment demand of different voltage levels. The measurement results of investment demand are brought into the investment impact calculation model to measure whether the company's benefit level under the investment demand scheme meets the overall performance objectives of the company; thirdly, it constructs different. The investment motivation of the project is analyzed from four aspects of power supply access, meeting new load, solving heavy overload and strengthening grid structure. The key indicators that can reflect the demand of power grid construction are selected according to 500kV, 220kV, 110kV and 35kV, and the investment demand index evaluation is formulated Price system.
