Economic quantification model of power distribution network project for power distribution network operation performance improvement degree

Abstract

The invention discloses an economic quantitative model for evaluating the improvement degree of a power distribution network project on the operation performance of a power distribution network. The model is used for evaluating the improvement degree of the operation performance of the power distribution network project based on project investment cost so as to help investors to analyze the cost performance of a target power distribution network project and the overall profitability of the society. The model comprises benefit increase brought by power grid performance improvement in four aspects of power distribution network power supply reliability improvement, power grid improvement, power supply capability enhancement and energy utilization enhancement caused by a power distribution network project, and project investment construction cost and later operation and maintenance cost. Economic quantitative analysis is performed on the power grid operation performance improvement broughtby the project based on the economic cost of the distribution network project so that the defect that the actual economic 'benefit' of the distribution network project is difficult to quantify due tothe fact that the performance improvement in the technical aspect of the project and the investment cost in the economic aspect are separately compared by the existing model can be compensated.

Description

technical field [0001] The invention relates to the field of evaluating the degree of improvement of distribution network operation performance in the electric power industry, in particular to the quantitative analysis of the specific economic benefits and costs brought about by the distribution network project to improve the distribution network operation performance. Background technique [0002] The post-project evaluation index system of distribution network projects generally evaluates distribution network projects comprehensively from the aspects of distribution network project implementation, distribution network operation performance after implementation, economic investment costs and benefits, social impact and technological development. Among the various indicators, the core point that investors are most concerned about is the two items of economic investment cost benefit after the implementation of distribution network operation performance improvement machine.

[0007] 3. The existing model mainly focuses on the benefit calculation of the project itself to the distribution network, and does not clearly reflect the cost increase or decrease of subsequent projects caused by the project. For example, integrated pipe corridors, reserved corridors, etc. affect later projects The project content of the construction;

[0008] The existing economic model mainly focuses on the absolute amount of benefits caused by investment, and it is difficult to reflect the increase in benefits brought about by each unit investment cost. In the case of limited funds, it is not friendly for investors to consider the cost performance of the project
