Optimal Scheduling Strategy of Multiple Microgrids Based on Improved Grey Wolf Algorithm

In order to alleviate the increasingly prominent energy problems and environmental problems, clean energy based microgrid technology has been widely studied and applied. Aiming at the coordination and optimization scheduling problem of multi-microgrid, the power transaction mechanism of multi-microgrid system is designed from the two aspects of multi-microgrid energy interaction and economic operation. Firstly, the two-layer scheduling mathematical model of multi-microgrid is established. Then, the improved Gray Wolf algorithm PSO-GWO is proposed and applied to the optimal scheduling problem of multiple micro networks. Finally, through simulation experiments, PSO-GWO, PSO and GWO are applied to solve the mathematical model of multi-microgrid optimal scheduling respectively, which proves that the established multi-micro-grid double-layer optimal scheduling model is feasible and effectively promotes the economic and stable operation of multi-micro-grid system.
