Abstract

Battery energy storage systems (BESSs) integrated with  renewable  energy  resources  are  considered  as  necessary solutions  for  economical,  technical  and  quality  aspects.  A  BESS  requires  a  power  conditioning  system  (PCS)  which  permits  both active and reactive power to be generated. In this paper, a wind-vanadium  redox  battery  (W-VRB)  station  is  considered  as  an  independent  power  producer.  The  profit  of  this  producer  is  maximized   by   solving   a   constrained   dynamic   optimization   problem in a day-ahead electricity market depending on real-time electricity   prices.   Then, the   reactive   power   compensation   capability   of   this   station   for   fulfilling   the   recent   technical   guidelines  is  estimated.  A  numerical  case  study  is  presented  to  illustrate  the  proposed  method.  It  can  be  concluded  that  a  large  amount   of   reactive   power   can   be   achieved   by   an   optimal   operating strategy for the W-VRB station.
