Method for analyzing and optimizing reliability cost/benefit precision of power supply

Abstract

The invention belongs to the field of an electric power system, in particular relating to a method for analyzing and optimizing the reliability cost / benefit precision of power supply. In the method, when a distribution network plan is carried out with the improvement of power supply reliability as a target, a reliability cost / benefit analysis curve can be obtained during individual implementation of each measure through actually analyzing various reliability improvement measures by utilizing the method; then the curves corresponding to the various measures are combined to formulate a reliability optimized strategy in combination with various measures by utilizing a classical reliability cost / benefit precision analysis theory of power supply; a reliability optimized path is selected from the combined curve by utilizing the strategy and can be further analyzed into the actual investment of each optimized measure, and further an implementation scale required for each measure can be obtained; and finally, the implementation scale is put into a specific scheme by combining the actual condition of a distribution network.

Description

technical field [0001] The invention belongs to the field of power systems, and in particular relates to a cost / benefit lean analysis and optimization method for power supply reliability. Background technique [0002] The power outage of power users caused by unreliable power supply may not only bring serious economic losses and adverse social impacts to users, but also bring economic benefits to power supply companies due to less electricity sales and compensation for power outage losses of users. But for power supply enterprises, improving the reliability of power supply and improving the economic benefits of enterprises are often contradictory. What reasonable combination of measures should be taken to improve the reliability of power supply in order to obtain the best level of reliability at a reasonable investment cost; Cost / benefit analysis to make decisions. [0003] In order to facilitate the measurement and calculation of the social and economic benefits generated...

AI Technical Summary

Problems solved by technology

The reason is mainly due to the fact that there are many factors affecting the reliability of power supply (mainly divided into four categories: network, equipment, technology, and management, and each category can be further subdivided). It is difficult to determine the reliability cost and the reliability benefits it may bring, and the reliability costs / benefits are different in different regions at different development stages, which makes the theoretical model of power supply reliability cost / benefit analysis feasible in engineering practice. Poor performance, difficult to carry out practical application
