Power system dynamics
If conventional power generation with synchronous generators is
on a large scale replaced with wind turbines that use either
asynchronous squirrel cage induction generators or variablespeed
generation systems with power electronics, the dynamics of
the power system will at some point be affected, and perhaps its
stability, too.
By taking adequate measures, the stability of the power system
can be maintained while increasing the wind power penetration.
For example, constant-speed wind turbines can be equipped with
pitch controllers in order to reduce the amount of over-speeding
that occurs during a fault; by combining them with a source of
reactive power (e.g. static condenser or static VAR compensator)
to supply the large amount of reactive power consumed by a
squirrel cage generator after a fault; or by changing the
mechanical and/or the electrical parameters of the turbine.
