| Summary: | This paper presents a number of controlling techniques that can used in extracting the wind energy from a wind prime mover. The extraction of wind energy bears in mind the target of matching the electric power needed by an electric generator with the maximum possible output power of a wind motor. The system studied consists of a wind motor model driving an electric generator unit. The electric generator considered can be one of the two types: 1- a separately excited DC generator and 2- isolated self-excited induction generator. Both generators were thought to be feeding a resisistive load. Steady state performance of each controlling technique is analysed and validated via computer simulations. Interesting results are encountered in the case of using the induction generator Keywords: Renewable energy resources, Optimzation of wind energy, Chopper, DC/DC Converter, Static Var Compensator (SVC), Induction generators
