AB  - Owing  to  generation  and  demand  mismatch,  thefrequency deviation and the rate of change of frequency (RoCoF)may  become  drastic  at  times  in  an  islanded  micro-grid.  This  isdue  to  increased  penetration  of  non-inertial  renewable  energysources  that  brings  down  the  system’s  resilience  to  any  kind  ofdisturbance. Therefore, efficient control algorithms are requiredto  mimic  the  inertial  behavior  of  a  conventional  synchronousmachine  to  arrest/limit  any  sudden  change.  This  work  focuseson  frequency  regulation  of  microgrid  during  transient  condi-tions  by  means  of  fast-responding  external  energy  reserve.  Thecharacteristics  of  a  weak  grid  has  been  studied  and  simulatedthrough  modeling  a  Virtual  Synchronous  Machine  (VSM).  Aninverter model is also developed to integrate the Energy StorageSystem (ESS) to the grid and a Double Second-Order GeneralizedIntegrator  Phase  Locked  Loop  (DSOGI-PLL)  is  implementedthat  is  capable  of  synchronizing  the  system  under  distortedand   unbalanced   situation.   A   new   technique   to   estimate   thefrequency  of  the  microgrid  is  reported.  A  simple  proportionalcontroller  based  approach  for  different  level  of  pulsed  powerinjection  (using  ultracapacitors  and  batteries)  is  proposed  andsimulated using MATLAB. Experimental demonstration is madeusing  batteries  only  but  with  two  different  current-limits.  Thecontroller  is  implemented  using  dSPACE1103.
