Wind farms

Customer challenges

Increased integration of the wind energy into the power grid impacts the grid’s reliability, due to the inherent variable and uncertain nature of wind power. Several factors contribute to such variability and uncertainty. For instance, more wind power can be available during low load conditions and vice versa making wind power as non-dispatchable resource of electricity.  In addition, most of the larger wind farms are often located far from the main grid thus the produced surplus energy may not be added to the transmission network due to transmission constraints. When the penetration of the wind industry increases, the issues of instability and poor reliability of the system are expected to worsen. Along with these variability and uncertainty changes, the wind farm can also suffer from different kind of power quality issues such as Low Voltage Ride Through (LVRT) and harmonic distortions among others.


  • Capacity firming
  • Output smoothing
  • Time shifting
  • Frequency regulation
  • Voltage regulation
  • Harmonic distortion mitigation
  • Congestion management
  • Low Voltage Ride Through (LVRT)

Customer benefits

The key benefits of improving power quality in renwable energy include:

  • More profitable wind farm operations
  • Defer investments for upgrade of transmission and distribution grids
  • Excellent Low Voltage Ride Through (LVRT)
  • Compliance with other demanding grid code criteria
  • Enhanced grid stability with increased Integration of wind generation
  • The control of reactive power/voltage with a STATCOM at the grid connection point instead of individual DC/AC converters can reduce losses
