Multistage comprehensive evaluation method for power distribution network planning scheme

Abstract

The invention provides a multistage comprehensive evaluation method for a power distribution network planning scheme. The multistage comprehensive evaluation method comprises the steps of firstly, based on the research result of the existing power distribution network planning evaluation field, establishing the comprehensive evaluation index system of the power distribution network planning according to objectivity, systematicness, practicability, scientificity and other rules; and providing the conception of the desirable power distribution network evaluation index value, wherein the index can be set according to the actual conditions and power distribution network development target and the like of regions and can be used as a comparison object of the current power distribution network situation and the planning scheme evaluation. Through the method and flow, not only can the annular power distribution network of the planning target be comprehensively evaluated, but also the integrated performances of the other multiple stages of the power distribution network planning scheme can be evaluated, the evaluation results can represent the year-by-year evolution process of the power distribution network planning scheme, and the time sequence reasonableness of deploying construction projects in the planning scheme, thus being beneficial for planning personnel to correcting the weak links of the planning scheme, enabling the planning scheme to be more scientific and reasonable so as to ensure the safe and stable running of the power distribution network.

Description

technical field [0001] The invention belongs to the technical field of power grid planning evaluation, and in particular relates to a multi-stage comprehensive evaluation method for a distribution network planning scheme. Background technique [0002] A scientific and reasonable planning scheme is the basic basis for the construction and transformation of the distribution network, and it is also an important prerequisite for the operation of the distribution network to meet the goals of safety, economy, and reliability. After the distribution network planning scheme is determined, a comprehensive evaluation of it will help decision makers choose the optimal scheme from many planning schemes, and improve the planning scheme according to the evaluation results, which is conducive to the further improvement of the comprehensive performance of the power grid. promote. [0003] Comprehensive Evaluation (Comprehensive Evaluation, CE) refers to making a global and holistic evaluat...
