Abstract

The swift increase in the number of electric vehicles (EVs) brings considerable prospects and difficulties for contemporary power distribution networks. This paper presents the performance evaluation of a 20 kW bidirectional EV charging station designed to facilitate both Grid-to-Vehicle (G2V) and Vehicle-to-Grid (V2G) power flow for enhanced smart grid support applications. The proposed topology integrates an AC/DC bidirectional converter interfaced to the 415 V, 50 Hz three-phase utility grid through a precision-designed LCL filter, followed by a non-isolated bidirectional DC/DC converter managing the 400 V, 50 kWh lithium- ion EV battery pack via a 700 V regulated DC link. A grid-following inverter control strategy employing a phase-locked loop (PLL) for synchronization, PI-based DC bus voltage regulation, and dq-frame current control ensures unity power factor operation under both charging and discharging modes. Comprehensive MATLAB/Simulink simulations confirm stable bidirectional power transfer with a peak system efficiency of 96.4% at rated load in G2V mode and 95.8% in V2G mode. The measured total harmonic distortion (THD) of the grid current is 2.87%, well within the IEEE 519-2022 limit of 5%. During V2G operation, the station delivers up to 18.5 kW of active power and ±9 kVAR of reactive power support to the grid. The results demonstrate that the proposed system effectively supports peak shaving, reactive power compensation, and frequency regulation, underscoring its viability as a smart grid asset. The outcomes of this study validate the technical and economic case for large-scale bidirectional EV charging infrastructure deployment.
