Microgrid Economic Dispatch Based on Multipass Iteration Particle Swarm Optimization Algorithm

Considering the time of use(TOU) power price differences and the energy trading with the main grid,and targeting at minimum power generation cost,two economic operation models are established based on the microgrid system composed of renewable energy resoures(wind turbines,photovoltaic cells,gas turbines and storage batteries) to solve the economic dispatching problem under the integrated microgrid and planned island operation mode.Meanwhile, based on the improved particle swarm optimization(PSO),a multipass iteration particle swarm optimization(MIPSO) algorithm is proposed,suitable for multi-period and dynamic optimization,to solve the dispatching problem. Finally,a calculation simulation proves that the improved algorithm is feasible and effective.
