AB  - This paper presents the development of a high-performance electric vehicle (EV) synchronous reluctance motor (SynRM) drive and its vehicle-to-grid (V2G) and vehicle-to-microgrid (V2M) bidirectional operations. The EV motor drive boostable DC-link voltage is established by a battery through a bilateral interface boost-buck DC-DC converter for good driving performance over a wide speed range. The motor efficiency is 92.3% near the rated load. In idle conditions, the embedded interface converter and inverter of the motor drive can be arranged to perform the G2V/V2G operations by adding external LC low-pass filters. The on-board battery can be charged from the mains in G2V mode with good line-drawn power quality. Alternatively, in V2G mode, the battery can send the preset power back to the utility grid with good current waveform quality. Besides, the same schematics can also conduct the M2V/V2M operations. A wind switched-reluctance generator (SRG) based microgrid is used as a test plant. The EV mobile energy storage application to microgrids is successfully offered through the arranged controls for effectively utilizing renewable sources. The measured results verify the normal operations with satisfactory performances for all power stages and operation cases.
