Power distribution network rolling planning post-evaluation method based on fuzzy analytical hierarchy process

Abstract

The invention discloses a post-evaluation method for distribution network rolling planning based on fuzzy analytic hierarchy process. Calculate the impact factor of equipment utilization rate utilization, so as to introduce the equipment utilization rate factor reflecting the actual performance output efficiency on the relevant secondary indicators; finally, according to the weight of the first-level indicators and the second-level indicators, calculate the quantitative value of the first-level indicators and the weight of the second-level indicators The total quantitative evaluation value. In addition, a calculation method of the weight sensitivity of the first-level index of the proposed distribution network rolling planning post-evaluation model is also given, which can show the value range of the first-level index with the same order. In general, the above methods can provide scientific quantitative analysis basis for distribution network planning and investment decision-making.

Description

technical field [0001] The invention relates to a post-evaluation method for distribution network rolling planning based on fuzzy analytic hierarchy process, and belongs to the technical field of distribution network planning. Background technique [0002] Generally speaking, my country's distribution network planning period is divided into three stages: short-term (5 years), medium-term (10 years) and long-term (15 years and above). In order to better connect the 5-year plan with the annual plan, it is necessary to continuously track the implementation of the mid- and long-term plan, flexibly adapt to social development, market demand and technological progress, and adjust the plan in a timely manner. It is necessary to adopt the rolling planning method: namely In the near future (5 years), the high-voltage distribution network should undergo rolling revisions every year, and the medium and low-voltage distribution networks should carry out rolling revisions to the planning...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: a post-evaluation method of distribution network rolling planning based on fuzzy analytic hierarchy process is proposed, which overcomes the problem of difficult inspection and judgment matrix of traditional analytic hierarchy process, and enriches the rolling planning of distribution network The quantitative evaluation model solves the problem of scientific setting of the weight of each index in the above model, which is helpful for quantitative analysis of the difference between judgments, strategies, goals and actual results in rolling planning, and provides scientific quantification for later distribution network planning and investment decision-making Analysis basis
