Centralized Multi-Functional Power Management of an Integrated Microgrid–Electric Vehicle Charging Station

Various power management systems for microgrids (MGs) integrated with electric vehicle (EV) charging stations (CSs) have been designed so far, each addressing different aspects of grid-connected or off-grid operation. However, no previous research has developed multi-objective power management schemes that encompass all possible operating modes, including MG operation with the grid (G) without CS, CS operation with G without MG, MG-CS integrated operation with G, MG and CS autonomous operation in off-grid mode, and the interaction between MG and CS without G. In this article, innovative multi-functional power management strategies utilizing centralized control system have been modeled and designed for the aforementioned operational modes and simulated in the time-domain nonlinear environment of the MATLAB-SIMULINK. The results indicate the effective performance of different schemes in various operational states.
