The paper presents a nonlinear approach, using a two-mass model and a wind speed
estimator, for variable-speed wind turbine (WT) control. The use of a two-mass model is …

The increased integration of wind power into the electric grid, as it occurs today in Portugal,
poses new challenges due to its intermittency and volatility. Wind power forecasting plays a …

Modular generator and converter topologies are being pursued for large offshore wind
turbines to achieve fault tolerance and high reliability. A centralized controller presents a …
