Sustainable DC-microgrid control system for electric-vehicle charging stations

As renewable energies and electric-vehicles increase in popularity, their interaction with existing grids becomes inevitable. This paper proposes a power management system to distribute acquainted power in a dc-microgrid supplying energy to a fleet of electric vehicles (EVs) used as taxis. A dynamic dc-microgrid model is used to validate the algorithm, including the dc-dc converters that interact with the grid and a PI controller to regulate the dc voltage. The proposed algorithm and voltage control are validated with several test cases.
