WIND ENERGY-GRID STABILIZATION USING A DYNAMIC FILTER COMPENSATOR

Abstract

Economic  electric  energy  generation  using  wind  energy production  has  been  rapidly  growing  for  the  last  three decades.  However,  the  integration  of  a  large  wind  scheme can  pose  inherent  voltage  instability  and  power  quality problems.   The   paper   presents   the   impact   of   a   Novel Dynamic  FACTS  Compensator  Scheme  DFCS  developed by  the  Second  Author  on  voltage  level  stabilization  and power quality  enhancement of  Wind-Grid connected  green energy   system.   The   Wind   Energy   Conversion   System comprises   four   key   parts.   The   wind   farm,   induction generator  and  DFCS  scheme  and  the  novel  Multi  loop dynamic  error  driven  coordinated  controller    developed  by the  second  Author  to  ensure  voltage  stabilization,  power quality  enhancement  and  minimal  inrush  transients  and excursions    under    normal    operation    ,    wind    velocity excursions  and  hybrid  motorized-linear  –nonlinear  load disturbances.  The integrated wind-grid scheme with four subsystems has been  digitally  simulated  using  the  Matlab  Simulink/Sim-Power  software  environment.    The  DFCS  scheme  with  the coordinated    dynamic    error    driven    hybrid    controller developed   was   fully   validated.   The   digital   simulation results  have  indicated  that  the  novel  new  DFCS  Filter Architecture   and   Multi   loop   controller   did      maintain voltage  stabilization,  enhance  power  quality  and  improve energy utilization.
