Application of Cloud Theory to Optimal Planning of Substation Locating and Sizing
摘要
Abstract
The optimizational planning of locating and sizing for a distribution substation is a large combinatorial optimization problem. To solve this problem, a cloud theory optimization algorithm (CTOA) is proposed based on the outstanding characteristics of cloud in transforming a qualitative concept to a set of quantitative numerical values, and in combination with the principle of “survival of the fittest” of the genetic algorithm. The core thought of the algorithm is that the hereditary characteristic of the parent individual first is represented by the expected value of cloud, then the degree of the heredity and mutation is controlled by entropy and hyper-entropy of the cloud, and transformation between the qualitative concepts and their quantitative expression is realized by normal cloud, so as to realize the reproduction. With the instructions of the qualitative knowledge,the extent of the searching space is self-adjusted, and the possibility of prematurity and the probability of trapping in local best optimization are greatly reduced. The proposed CTOA is tested by a realistic planning project to verify the effectiveness and feasibility. The calculation speed and search accuracy of CTOA are obviously superior to those of the improved adaptive genetic algorithm (IAGA) and refined multi-team particle swarm optimization algorithm (RMPSO), without the process of coding and crossover and easy implementation. The method proposed has a promising application in large-scale practical problems.关键词
