Wind Energy Systems Solutions For Power Quality And Stabilization



This book provides fundamental concepts of wind energy conversion systems and discusses grid integration and stability issues, methods of transient stability enhancement and minimization of fluctuations of power, and frequency and voltage of wind generator systems. Recently, electricity generation using wind power has received much attention all over the world.


Wind energy is a free, renewable resource, so no matter how much is used today there will still be the same supply in the future. Wind energy is also a source of clean, nonpolluting electricity. Unlike conventional power plants, wind plants emit no air pollutants or greenhouse gases. Induction machines are mostly used as wind generators.

However,induction generators have stability problems similar to the transient stability of synchronous machines.During a fault in the power network,rotor speed of the wind generator goes very high, active power output goes very low, and terminal voltage goes low or collapses down.
Usually the wind generator is shut down during these emergency situations. Recent tradition is not to shut down the wind generator during a network fault but to keep it connected to the grid through appropriate control.

This clearly indicates that wind generator stabilization is necessary during network faults. Again, even though there is no fault in the network, due to random wind speed variations, output power, frequency, and terminal voltage of wind generators fluctuate. However, consumers desire to have constant voltage and frequency.
Therefore, some control means are necessary to minimize power, frequency, and voltage fluctuations. This book discusses several means to enhance the transient stability of wind generator system and also explains the methodologies for minimizing fluctuations of power, frequency, and voltage.
