More electrical energy from renewable sources means that more ancillary services and grid support services are provided by them. This work examines the ability of a commercial wind turbine to provide power-frequency control and AGC(automatic generation control). Power-frequency control opposes changes in grid frequency via active power and operates on time scales of 1 –2 seconds. AGC is used by grid operators to maintain the demand-supply balance What Where via small changes in generator active power output. This work was a collaboration between a system operator, a wind turbine OEM and an independent research institute. These results are useful to other grid operators as they represent the performance of commercially available wind turbines as opposed to a simulation.
