ABSTRACT


Electric vehicles (EVs) have become a progressive technology in the mainstream transportation solution. However, opportunities to recharge the vehicle battery have become a problematic subject. This paper proposes photovoltaic (PV) powered grid connected two plug spot EV charging system aided with buck/boost bidirectional charging with local energy storage unit (ESU). The bi-directional converter with fuzzy controller used to provide a regulated output for ESU to charging (charging station to ESU) and discharging (ESU to the grid). The system structure of a DC microgrid and its unit functional models are first introduced in this paper. Second, depending on the various power demand scenarios, an appropriate control action is maintains the power for charging. The proposed fuzzy is operating in a decentralized manner for maintaining the power distribution between microgrid DC-link and ESU. The MATLAB system simulation and laboratory scale of two EV charging plug spot DC microgrid has been studied and verified under various microgrid conditions, and the results are confirmed the proposed charging station upshot.


Keywords: Plug-In Electric vehicle (EV), DC to DC converter, DC microgrid, fuzzy logic and EV charging Station
