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.
