Modern wind power plants may consist of tens to hundreds of individual wind turbine generators. Usually a supervisory control at plant level is applied to regulate the terminal behavior of the complete plant, by dispatching commands for active and reactive power or voltage control to the individual wind turbine generators.<br /></p><p><br /></p><p>The work of defining sophisticated models for wind power plants is currently underway.  Until that is complete, a rudimentary representation of plant level controls is defined for the simulation of large wind plants in the form of a simplified plant control model.  The simplified plant control model only covers voltage and/or reactive power control features, as these are considered most important for application in large-scale power system transient stability studies.<br /></p><p><br /></p><p>The simplified plant control model is intended to be used with Type 3 and Type 4 wind turbine generator models. These types are based on power electronic converters and have therefore the ability to continuously control their terminal voltage. Type 1 and Type 2 wind turbine generators do not have this ability.<br /></p><p><br /></p><p>The typical use envisaged for this plant control model is where the whole wind power plant is represented in an aggregated fashion by a single turbine model instance.  An appropriate equivalent of the collector system is then required.<br /></p><p><br /></p><p>More information is contained in IEC Standard 61400-27-1 Annex C.<br /></p>
