ABSTRACT

This chapter presents a complete mathematical modeling for the components of the wind energy conversion system, including a DFIG as a generation unit for electrical energy, a wind turbine as a prime mover, and a three-phase induction motor as an isolated load. First, the detailed mathematical model of the DFIG is presented in the general rotating frame to give an extra freedom when applying the control. After that, the wind turbine system and its power management unit, which adopts the maximum power point tracking (MPPT) principle to optimally exploit the wind energy, are modeled and described in a detailed manner. Following that, the mathematical model of the isolated load to be fed by the DFIG under standalone operation is described. The load under study is a three-phase induction motor (IM) as an emulator to a realistic loading condition.
