Embodiment 1

[0039] This embodiment takes figure 1 The shown smart distribution network performs automatic terminal configuration, and the distribution automatic terminal configuration method in this embodiment includes the following steps:

[0040] The first step is to establish the optimization objective function of the scheduled smart distribution network as minC A =min(C G +C M +C L ), where C A Indicates the total cost of the equivalent annual value of the planning scheme, C G Indicates the annual value of primary and secondary equipment investment, C M Indicates the annual operating cost, C L Indicates the loss cost caused by the annual power outage;

[0041] in, C G = C G 1 + C G 2 = N · P F (...

Embodiment 2

[0052] This embodiment is an improvement on the basis of Embodiment 1. The difference from Embodiment 1 is that the constraints in this embodiment also include reliability constraints, and the reliability constraints refer to the configuration scheme corresponding to each individual. The reliability index is greater than the preset minimum reliability index, and the reliability index includes the reliability index of each load point and the reliability index of the smart distribution network; the calculation method of the reliability index of the configuration scheme corresponding to the individual as follows:

[0053] (1) The lines of the intelligent distribution network are divided into several blocks according to the positional relationship with the section switch, tie switch and user boundary switch, and all blocks are numbered, and the equivalent failure rate is calculated for each block and the equivalent annual mean outage time;

[0054] (2) Take the block as the unit,...

Abstract

The invention relates to a configuration method of a distribution automation terminal. The method includes: firstly, an optimization objective function is established, positions of to-be-installed switches are encoded, the optimization objective function is regarded as a fitness function, an initial population including a plurality of individuals is randomly generated, the fitness function of each individual is calculated, the fitness of the individual is obtained, and the individual with the lowest fitness in the initial population is finally found as the optimal individual; the next generation of population is obtained via selection, crossover, and mutation operation of the initial population, the fitness function of each individual is calculated, and the individual with the lowest fitness in the population is obtained as the optimal individual of the population; and if the mutual differences between the fitnesses of the optimal individuals of 10 continuous generations of populations are all less than a preset threshold, automation terminal configuration of the intelligent power distribution network is accomplished. According to the method, the economy and reliability of the configuration of switches and the distribution automation terminal of the intelligent power distribution network can be optimal.

Description

technical field [0001] The invention relates to a distribution automation terminal configuration method in intelligent distribution network planning, and belongs to the technical field of distribution automation. Background technique [0002] Distribution automation is based on the primary grid and equipment of the distribution network, with the distribution automation system as the core, and comprehensively utilizes a variety of communication methods to realize the monitoring and control of the distribution network, and through information integration with related application systems , to realize the scientific management of power distribution system. Distribution automation terminal (also known as "distribution terminal") is a general term for various remote monitoring and control units installed on the medium-voltage distribution network site. network unit, distribution transformer, etc. Distribution automation is an important means to improve the reliability and qualit...
