In this work, it is shown that it is possible to operate a wind energy conversion system (WECS) based on a doubly fed induction generator while operating in a different mode than maximum power tracking. Here, using the recent results on the steady state solution of the torque balance transcendental equation, analytical expressions for all the state variables of the WECS are obtained. In this fashion, closed‐form online reference trajectories for the system variables are presented. These analytical formulas can be used to perform power tracking control into the safe operational region of WECS. Moreover, realistic generic case studies are described to depict how these results are useful in systematically assessing the secure operating regime for both, the electric and mechanic components of the WECS.
