Support for spinning reserve from DFIG based wind turbines

With the increased penetration of wind power, wind turbines are now expected to provide ancillary services presently performed by large synchronous generators. Among the ancillary services, frequency duties are vital and a number of papers are available in the literature to demonstrate the possibility of using DFIG based wind turbine for inertia, primary and secondary frequency support. This paper describes the possibility of using DFIG based wind turbine for supplying spinning reserve. The mode of operation is described and simulation results are included.
