Description

technical field [0001] The project of the present invention relates to a micro-grid capacity optimization addressing method, especially a micro-grid capacity optimization addressing method based on an improved ant colony algorithm. Background technique [0002] At present, the capacity optimization of the microgrid has always been a major problem in the construction of the microgrid. The unreasonable distribution of micro-sources in the micro-grid will have a certain impact on the power consumption of lines or users, and the external environment will also affect the power generation performance of micro-sources. At present, some intelligent optimization algorithms have been applied to solve this problem, such as particle swarm algorithm, genetic algorithm and differential evolution algorithm. However, the particle swarm optimization algorithm is prone to fall into local optimal solutions when dealing with discrete problems such as micro-source placement; the genetic algorit...
