The Value of Dynamic VARs to Allow a Wind Farm to Meet a Utility´s Interconnection Requirements

Throughout the world, renewable energy in the form of wind farms is being installed in ever increasing numbers. Up to this point, keeping these wind farms on-line for faults on the utility transmission systems has been quite difficult. While wind turbine manufactures are continuing to make their machines more fault tolerant, there is also another method to help these machines ride through faults. Analysis has shown that dynamic VARs from a centralized FACTS device are very effective in providing the wind farms with fault ride thru capability. This paper presents the methods of designing and sizing an installation of a dynamic VAR compensator (DVC ) on a utility system to meet the utility´s interconnection requirements
