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.

An additional energy storage system, power or pitch angle control are thus
required to cope with the unsteady output.

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.

For example, it has high energy density, produces no pollution and can
last for a long time.

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 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. (我必須承認，最後這句，完全看不懂原文想說什麼)
