US Patent Issued to National Technology & Engineering Solutions of Sandia on Jan. 27 for "Systems and methods for optimal phase shift between dynamic control actions for wind turbines" (New Mexico Inventor)

ALEXANDRIA, Va., Jan. 28 -- United States Patent no. 12,535,055, issued on Jan. 27, was assigned to National Technology & Engineering Solutions of Sandia LLC (Albuquerque, N.M.).

"Systems and methods for optimal phase shift between dynamic control actions for wind turbines" was invented by Kenneth Brown (Albuquerque, N.M.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Dynamic wake control (or dynamic induction control) is used to promote wake breakdown and recovery behind a wind turbine that improve wind farm performance/efficiency. Constructive interference is created by simultaneously performing harmonic rotor speed control and harmonic collective pitch control so that the phase of the rotor speed perturba...
