Power Management for DC Micro grid with Hybrid Storage System Fed Induction Motor Drive

Abstract

Continuously increasing demand of Microgrid with high penetration of distributed energy generators, specially focused on renewable energy sources is modifying the traditional structure of the electric distribution grid. In addition, DC micro grids diverted the attention of researchers and power electronics industry in recent years to stimulate renewable energy technologies (RETs) and distributed energy resources (DERs) deployment and encouraging technological innovation to reduce green house gas (GHG) emission and achieve energy security and independence to meet the growing electricity demand. So for many studies have been done on successful integration of RETs and DERs, operation and control, protection and stability issues, simultaneously and satisfactorily implemented during feasible operation of microgrid. Studies show that DC transmittable power can increase the system efficiency up as compared to AC. But still DC bus voltage fluctuation, power quality and flow during the transition between grid connected mode to islanded mode or transient load insertion which intend to DC microgrid instability are the problems which need to be investigated and resolved for the effective use of DC microgrid generation. In this concept DC microgrid voltage, power flow, power quality and energy management different controls and techniques are reviewed. This concept can be extended as Induction Motor drive Power management for DC Microgrid Application.
