The torque produced by the wind turbine reflects to the PMG
and low voltage produced by the PMG is rectified and boosted
using a boost converter in order to maintain an adequate DC
link voltage for proper working of the inverter. For this work,
the Maximum Power Point Controller (MPPC) control the
optimum speed of the generator for maximum power
production of the wind turbine and the Maximum Power Flow
Controller (MPFC) ensures the proper flow of power to the
grid by maintaining an adequate DC link voltage. A complete
schematic of the system is shown in Fig. 1 and the modeling is
described afterwards.
A wind turbine can be characterized by the non-
dimensional curve of power coefficient, C p as a function of Tip
Speed Ratio (TSR), λ, where, λ is given in terms of rotor speed,
ω s (rad/s), wind speed, w (m/s), and rotor radius, R w (m) as
