Abstract

The invention relates to a receiving-end grid optimal layering and districting scheme obtaining method which comprises the following steps: 1) obtaining a receiving-end grid initial districting scheme group on the basis of a Normal matrix spectrum bisection method; 2) establishing a layering and districting scheme evaluation model; 3) computing the evaluation index value corresponding to each districting scheme in the initial districting scheme group to form comparative sequences of the districting scheme, and carrying out non-dimension disposal on the comparative sequences; 4) obtaining the GRG coefficients zeta0i(k) of the comparative sequences and the grey relational weight wbetai of each evaluation index; 5) obtaining the AHP weight walphai of each evaluation index by adopting an analytic hierarchy process; 6) computing the overall grey relational degree rk of the districting scheme according to the grey relational weight and the AHP weight obtained in the step 4) and step 5); 7) taking the maximum districting scheme of the overall grey relational degree as the optimal districting scheme. Compared with the prior art, the receiving-end grid optimal layering and districting scheme obtaining method has the advantages of being simple in topology model and high in algorithm speed and reliability of results.

Description

technical field

[0001] The invention relates to a power distribution network system, in particular to a method for obtaining an optimal layered partition scheme of a receiving-end power grid. Background technique

[0002] Hierarchical and partitioned operation is an inevitable trend in the development of power grids. Research on the hierarchical and partitioned operation scheme of the receiving power grid can not only ensure the safe and stable operation of the power grid, but also create considerable technical, economic and social benefits.

[0003] At present, there are few domestic researches on the theory and method of power grid layering and partitioning, and the theoretical methods related to power grid partitioning are mainly derived from a three-level voltage control model proposed by the French Electricity Company (EDF) in the 1970s, which has been used in many It is applied in the national power grid. Among them, reasonable division of voltage control areas is the...
