The Doubly Fed Induction Generator based Wind Turbine (WT-DFIG) suffers from instability while steady-state operation if improperly controlled. This paper proposes and evaluates three Scalar strategies that ensure Maximum Power Point Tracking (MPPT) and stabilizes the WT-DFIG. Both of the generator electromagnetic torque – speed and the wind turbine mechanical torque-speed characteristics are taken into account. The proposed scalar control strategy is based on Rotor Voltage and Frequency Magnitude Control (RVFMC) function at any MPPT specified speed range and different operating conditions. The DFIG steady-state stabilized MPPT characteristic is first examined and evaluated in conjunction with the stator voltage. The corresponding developed torque components are classified into induction torque components and synchronous torque components. The induction torque impacts on stability while MPPT at steady state is presented, and further approved by the WT-DFIG MPPT dynamic model. Depending on a constrained the Rotor Voltage Angle (RVA), three Scalar MPPT control algorithms are constructed. The first one deals with maximizing the synchronous developed power (MSP), the second strategy optimizes the synchronous power to achieve higher stability at higher power capability (OSP) and the third strategy deals with gaining higher power at maximum efficiency (ME). The rotor voltage shift angle which may be considered as well as a load angle has been defined for each algorithm. Detailed performance characteristics are presented, compared and evaluated to recognize the gained power ratio, stability, and efficiency enhancement. The proposed techniques implementation is explained; the controller design and a simplified block diagram of the prescribed independent voltage and frequency reference generator block diagram are provided
