Problems solved by technology

[0003] In the past, the research on microgrid operation mainly focused on the microgrid system composed of wind, solar and other power generation units, without considering the impact of electric vehicles. With the large-scale use of electric vehicles, the irregular use behavior of users leads to the optimization of microgrids. Scheduling has undergone great changes. Therefore, in view of the uncertainty of renewable energy in the current micro-grid, providing a micro-grid optimal scheduling method for safe and economical operation of the micro-grid has become an urgent problem to be solved in the application and development of the micro-grid. important question

Abstract

The invention relates to an intelligent micro-grid optimization scheduling method of an improved particle swarm optimization algorithm. The problem of system energy uncertainty caused by renewable energy in a microgrid is solved. According to the method, annealing and variation ideas are introduced into the PSO algorithm, the global search capability of the particle swarm algorithm is improved byutilizing the probability kick characteristic of the simulated annealing algorithm, and meanwhile, the fine search capability of the particle swarm algorithm is improved by utilizing the characteristic of carrying out key search on a local area near an individual area by utilizing the Gaussian variation algorithm. According to the invention, economical efficiency and reliability of microgrid operation can be effectively improved.

Description
