Embodiment

[0616] The present invention is applied to carry out on-the-spot research, evaluation and analysis on the demonstration area of ​​the intelligent distribution network in the south-central area of ​​Hexi, Nanjing, and to carry out practical application in combination with the construction project of the Hexi intelligent grid. The total planned investment of the Hexi Smart Grid Demonstration Zone was about 630 million yuan, of which about 46 million yuan was invested in the transformation of the grid structure, which was mainly used to further improve the reliability of power supply. By analyzing the status evaluation results of the distribution network in the central and southern regions of Hexi, it can be seen that the scores of several related indicators related to grid transformation are very high, even most of them are 100 points, such as: 110kV, 35kV meet the proportion of N-1 main transformer, 110kV, 35kV meets the proportion of N-1 lines, medium voltage meets the proporti...

Abstract

The invention relates to an assessment method of efficient operation of an intelligent power distribution network. The assessment method comprises the steps of: (1) determining boundary conditions; (2) determining service objects; (3) building an assessment index system which includes a power distribution network safety index, a power distribution network reliability index, a power distribution network economical efficiency index, a power distribution network high operation quality index and a power distribution network intelligence index; (4) determining assessment index numerical values of single items; (5) scoring for single items of assessment indexes; (6) performing comprehensive scoring of the assessment index system; and (7) judging whether efficient operation of the power distribution network is achieved according to a comprehensive score of the assessment index system in Step (6). The assessment method for efficient operation of the intelligent power distribution network in the invention has a relatively wide range of application, can comprehensively assess the operating state of the intelligent power distribution network, and an assessment result provides an importance basis for decision-making work of power grid dispatching, planning and operation management personnel.

Description

technical field [0001] The invention relates to an evaluation method in the field of intelligent distribution network analysis, in particular to an evaluation method for efficient operation of an intelligent distribution network. Background technique [0002] The smart grid is a complex and huge system engineering, and the practice of the smart grid is still in its infancy worldwide. Comprehensive and scientific evaluation of the comprehensive benefits of the smart grid, timely discovery of deficiencies in the construction and operation of the smart grid, and the realization of smart grid construction The balanced development of technology and economy in China has great practical significance for correctly guiding the planning, construction, operation and management of smart grid. On the one hand, the smart grid is an upgrade and transformation based on the traditional grid. It has all the functions of the traditional grid; Various functions of the traditional grid. Theref...
