دانلود Wind Power Plant Voltage Control Optimization with Embedded Application of Wind Turbines and STATCOM

Abstract

Increasing  wind  power  penetration  and  the  size  of Wind  Power  Plants  (WPPs)  brings  challenges  to  the  operation and  control  of  power  systems.  Most  of  WPPs  are  located  far from load centers and the short circuit ratio (SCR) at the Point of  Connection  (POC)  is  low,  which  means  that  fluctuations  of  the wind power can cause voltage variations. An optimal voltage control  scheme  for  WPPs  with  STATCOMs  is  presented  in  the paper.  It  ensures  that  the  voltages  within  the  WPPs  and  at  the high voltage side of the WPPs are within the limits and maximizes  the  dynamic  Var  reserve  of  the  WPPs.  Case  studies were  conducted  with  the  simplified  Anholt  offshore  WPP  and the  case  study  results  demonstrate  the  efficacy  of  the  proposed optimal voltage control scheme.
