Abstract
A method and system for shutting down a wind turbine is presented. The method includes determining one or more pitch positions for one or more rotor blades of the wind turbine such that a sum of potential energy and kinetic energy in the wind turbine is minimized. The method further includes pitching the one or more rotor blades from an operating position to the determined pitch positions.
