Abstract

The present work proposes a coordinated power distribution control of wind-energy fed self-excited induction generator (SEIG) based low-voltage direct current (LVDC) autonomous microgrid. The battery and supercapacitor (SC) hybrid energy storage system (HESS) is interfaced with the common 48 V LVDC bus using a parallel-active configuration through two bidirectional converters. The prime idea of hybridization is to limit the instantaneous peak current demand and also to alleviate the charge/discharge stress during transients, thus reducing the size of the battery. The developed autonomous LVDC system with the supervisory power distribution control scheme (PDCS) is experimentally validated for different operating modes. The comparative experimental result analysis substantiates the efficacy of the proposed PDCS along with seamless transition between various modes.
