Abstract

Electric vehicles (EV) integrated with renewable energy will give way for the envisioned future for a pollution free environment. The charging infrastructure plays a major role in EV industry, thus leading EV technology to the next level. These charging infrastructures connected to hybrid microgrid are indeed to meet out their flexible and uninterrupted service. Nevertheless, the energy management strategy (EMS) of charging station connected hybrid microgrid is a challenging task. In this paper, a multiple PEVs charging point connected PV powered hybrid microgrid structure is proposed with their energy management algorithm to give the continuous supply to the utility loads including EVs changing points. The different modes of energy management strategies are developed for the proposed microgrid to offer the continuous power supply to the EV charging point. The proposed charging structure consists of Maximum Power Point Tracking (MPPT) DC-DC boost converter, AC-DC bidirectional converter for grid integration, energy storage unit (battery), DC-DC buck/boost converters to control the bidirectional power flow from PEV. The EMS is coordinating the EV charging and power distribution among PV, utility grid, energy storage unit, and multiple EV charging loads, based on the measured DC Bus voltage the unique control strategy is designed for the charging station. The proposed microgrid model is designed and simulated through MATLAB/Simulink. The simulation study and its results meet out the continuous charging performance for all microgrid conditions. The proposed experimental model is implemented using a PIC 16F877A microcontroller, and the experimental results were verified.
