摘要
Abstract
Based on electromagnetism-like mechanism （ELM） algorithm, a high fault-tolerant method for multi-objective power network planning is proposed. To enhance the performance of ELM algorithm, its global search ability of the basic model is improved by introducing the idea of passive congregation in. The measures such as adaptive weight, adaptive variation and elitist strategy are adopted to improve the convergence of ELM algorithm. For the power network planning in which the generation planning, substation locations and load demand are known, the multi-objective function reflecting economy and reliability index of power network is turned into single objective model to solve the minimum cost of network planning. Applying decimal coding to a 18-bus system, calculation results show that the proposed algorithm can effectively solve such a large-scale combinatorial optimization problem containing discrete variables and improve the overall satisfaction of the planning scheme. Comparison of simulation results from genetic algorithm and basic ELM algorithm show that the improved ELM algorithm possesses obvious advantages in search efficiency and fanlt-tolerance.关键词
