Abstract
This paper proposes a decentralized method for
nonlinear control of oscillatory dynamics in power systems. The
method is applicable for ensuring both transient stability as well
as small-signal stability. The method uses an optimal control law
which has been derived in the general framework of nonlinear
control using normal forms. The model used to derive the contr
ol
law is the detailed subtransient model of synchronous machines
as recommended by IEEE. Minimal approximations have been
made in either the derivation or the application of the control
law. The developed method also requires the application of
dynamic state estimation technique. As the employed control and
estimation schemes only need local measurements, the method
remains completely decentralized. The method has been demon-
strated as an effective tool to prevent blackouts by simulating a
major disturbance in a benchmark power system model and its
subsequent control using the proposed method.
