Embodiment 1

[0071] Such as figure 1 As shown, the power grid projects are divided into cross-provincial and cross-regional power transmission channel projects, power supply projects, power supply demand projects, grid structure optimization projects, and electric railway power supply projects according to their functional positioning. The specific composition of each power grid project is:

[0072] Inter-provincial and trans-regional power transmission channel projects include single-circuit inter-provincial liaison, double-circuit inter-provincial liaison, and multi-circuit inter-provincial liaison projects.

[0073] The power transmission project includes single-circuit power transmission, double-circuit power transmission, three-circuit power transmission, and power supply within the ring network.

[0074] Projects to meet power supply requirements include the formation of single-line power supply substations, the formation of double-circuit terminal power supply substations on the sam...

Abstract

The invention relates to an input-output evaluation method and a system of a power network classification project considering risks, the method including the following steps: according to the relationship between different project types, risk indicators and functional positioning, determining the risk indicators from the project contractor and the risk indicators from the power grid project itself, and constructing a risk evaluation index system based on functional positioning; according to the risk evaluation index system based on function orientation, establishing an input-output evaluationmodel of power grid classification project considering risk. Based on the established input-output evaluation model, the input-output of a specific power grid project is evaluated. The invention reasonably divides the power grid project according to the function type, defines the structure of the input and output of the power grid project, and clarifies the correlation relationship between the risk factors and the function positioning. Through establishment of the input-output evaluation model of the power grid classification project considering the risk, the investment decision can be assisted by the power grid company, and the investment scientificity can be improved according to the weakness of the project.

Description

technical field [0001] The invention relates to a risk-considered input-output evaluation method and system for classified items of a power grid, belonging to the field of electric power system asset management evaluation. Background technique [0002] The input-output evaluation of power grid classification projects that takes risks into account is the evaluation of the completion effect and benefit level of power grid projects with different functional orientations. With the determination of the national new energy development strategy, the grid-connected operation of a large number of renewable energy sources has increased the investment and operating costs of grid companies. At the same time, the gradual deepening of power reform and the entry of private capital projects have limited the profit margins of grid companies. Double pressure Forcing power grid enterprises to pay attention to investment benefits. At present, the evaluation and assessment of investment benefit...
