The calculation contains a large amount of data, and most of them have intersecting relationships, and the unsuitable leading information will reduce the optimization level of the calculation
3) There is a conflict between the number of collective categories and the convergence speed
The number of collective categories is closely related to the distribution position. The more uniform the individual distribution position is, the more the number of collective categories will be, and the probability of obtaining the best result will be higher, but it will consume more traversal time and reduce the convergence speed.
[0005] At the same time, whether the distribution network is properly arranged plays a key role in ensuring the safety and stability of the distribution network, but the distribution network arrangement is an extremely cumbersome improvement work, including the construction and selection of core equipment such as transformers and lines, etc., not only must meet the requirements of stable power increase Requirements, and make the distribution network design and operation costs the least, the process of obtaining the best results is very cumbersome, so designing a complete distribution network arrangement method is an urgent problem to be solved

Abstract
The invention discloses a distribution network arrangement method considering perfect behavior rule calculation. The method comprises the following steps: setting an initial parameter by using a behavior rulealgorithm, realizing iteration, and determining a tail end optimal travel path; determining reasonable values of a key point opening element alpha and an ideal opening element b in the behavior rulealgorithm so as to improve the behavior rule algorithm; and improving a distribution network arrangement strategy, and applying the improved behavior rule algorithm to the improved distribution network arrangement strategy so as to obtain an optimal arrangement strategy. The invention discloses a distribution network arrangement method considering perfect behavior rule calculation, and aims to prevent open monitoring during distribution network arrangement, enable any path of an individual to generate one type of arrangement strategy, optimize and adjust a key point opening element a, select a proper ideal opening element b, and realize a perfect behavior rule calculation process. The iteration time required by the method is reduced, and the efficiency is remarkably improved.
Description
technical field [0001] The invention relates to the field of distribution network arrangement, in particular to a distribution network arrangement method considering perfect behavior rule calculation. Background technique [0002] The specific content of the traditional behavior rules includes: if the goal is determined, the collective behavior path will gradually have rules, and the goal will be found according to the same shortest path. Because the individual generates heuristic elements related to the target source to feed back to the collective during the determination of the target, and gives key points along the path, the remaining individuals will combine the proportion of key points of all paths to determine the target position, and the proportion of key points is about high. Paths naturally attract more individual choices. As time goes by, more individuals will choose the same shortest path, making the key points of the path continue to rise. This behavior rule can...
