Europe is rapidly integrating high‑penetration wind turbines, which increasingly rely on fixed‑speed or doubly‑fed induction generators and must provide voltage and frequency control to meet grid‑code requirements. The study explores using blade‑pitch deloading of wind turbines to provide frequency response. The authors describe a power‑electronic control loop that synthesizes inertia in DFIG turbines and present a case study of an FSIG turbine equipped with frequency‑response capabilities. Grid codes now mandate that large wind farms supply control services, and the authors present a pitch‑control scheme that enables FSIG and DFIG turbines to deliver frequency response. © 2004 John Wiley & Sons, Ltd.
Abstract Throughout Europe there is an increasing trend of connecting high penetrations of wind turbines to the transmission networks. This has resulted in transmission system operators revising their grid code documents for the connection of large wind farms. These specifications require large MW capacity wind farms to have the ability to assist in some of the power system control services currently carried out by conventional synchronous generation. These services include voltage and frequency control. It is now recognized that much of this new wind generation plant will use either fixed speed induction generator (FSIG)‐ or doubly fed induction generator (DFIG)‐based wind turbines. The addition of a control loop to synthesize inertia in the DFIG wind turbine using the power electronic control system has been described. The possibility of deloading wind turbines for frequency response using blade pitch angle control is discussed. A pitch control scheme to provide frequency response from FSIG and DFIG wind turbines is also described. A case study of an FSIG wind turbine with frequency response capabilities is investigated.
