: In recent years, wind energy has shown a rapid growth as a clean and : inexhaustible energy source all around the world. But, it has the : intermittent power output bring about the grid fluctuation and difficult to : dispatching.For steady wind energy output that require auxiliary the fix Wind energy, however, is not without its problems. The intermittent power output, for example, creates grid fluctuations thereby making it difficult to dispatch the electricity generated by wind. : power control, pitch angle control or storage system. The first two only can An additional energy storage system, power or pitch angle control are thus required to cope with the unsteady output. : drop the power, but the storage system has rise and drop character, its : performance is more comprehensive. If want to make the wind turbine develope : to a generator that can be completely accepted dispatching, the storage : system was required. Among these strategies, the power and pitch angle controls can only decrease the power output, whereas the energy storage system can both increase and decrease the output, and therefore are generally considered as the better approach. Hence we believe that it is until all wind turbines are equipped with an energy storage system that wind can become a reliable option of green energies. : In today's energy storage equipment, Hydrogen, it has high energy density, : broad-spectrum, no pollution and long using life. Supercapacitors possess Hydrogen energy has many advantages among today's energy storage systems. For example, it has high energy density, produces no pollution and can last for a long time. : high efficiency and fast response characteristics.Therefore, this thesis : presents a model of PMSG-based wind energy conversion system which combines : with storage equipment that is used by hydrogen and supercapacitor. And add On the other hand, another storage system, the super-capacitors, is more efficient in energy conversion and comes with faster response characteristics. Hence in the thesis I propose a PMSG-based wind energy conversion model that implements both a hydrogen energy and a super-capacitor as the energy storage system. : the maximum-power-point-tracking control, the pitch angle control, the : storage switching and power drop control. Integrate to a controllable wind : generation system. Furthermore, this thesis applies standard deviation to : reach minimum storage equipment, which may decrese the cost of installation. The system equips with a maximum-power-point-tracking, a pitch angle, a storage switching and a power drop control. Such an integrated design allows our model to become a controllable wind generation system. The cost of the system deployment can be further reduced by applying the principle of standard deviation to minimize the energy storage equipment.
