Enhancing Induction Motor Recovery in Microgrids via Adaptive Voltage Regulation

This study proposes an adaptive voltage regulation strategy for battery energy storage system (BESS) converters to enhance induction motor speed recovery within a fault-triggered islanded microgrid. This is implemented by adaptively setting the voltage regulator reference point after sensing the low voltage condition. This new autonomous control strategy outperforms conventional voltage regulation by enabling induction motors to achieve a higher electromechanical torque for successful fault ride-through.
