A Wake Detector for Wind Farm Control [PDF]
, 2015 The paper describes an observer capable of detecting the impingement on a wind turbine rotor of the wake of an upstream machine. The observer estimates the local wind speed and turbulence intensity on the left and right parts of the rotor disk.

Cold Climate Wind: Challenges, Technological Solutions and Policy
WIREs Energy and Environment, Volume 15, Issue 1, March 2026.Operating wind farms in cold climates creates unique challenges for turbine designers, owners, and operators. Solving these challenges requires specific technological and policy solutions at all levels. ABSTRACT Cold‐climate wind power represents a major subset of onshore global capacity, with approximately one third of existing installations located ...
