摘要

This study examines how integrating electric vehicles (EVs) affects the best scheduling of charging and discharging procedures within microgrids, given the growing importance of microgrids and distributed power systems. This research aims to optimize EV charging/discharging cycles, using their travel trends, to evaluate their effects on energy losses, efficiency, and reliability of microgrids. This work employs the Enhanced PSO (EPSO) algorithm to meet several objectives, i.e., to reduce the electricity consumed from the main grid, to minimize the number of switch operations, to reduce power losses and to decrease the amount of time that the microgrid is connected to the main grid. Simulation results indicate that well-planned EV charging/discharging schedules can dramatically improve microgrid performance and decrease energy losses. There is opportunity to lower operating costs and improve the overall efficiency of networks by utilizing EVs as distributed energy storage and power transfer devices. This study offers methods for improving efficiency and decreasing loss in distributed energy systems and also presents innovative approaches to EV charging and discharging scheduling in conjunction with microgrid operation.
