Abstract :
The problem of model reduction by moment matching for multimachine power systems is addressed and solved using the recently introduced notion of moment for nonlinear systems. It is shown that the reduced order model can be used to construct asymptotic estimates for the unmeasured states. The theory is illustrated by means of simulation on a 2-machine power system.
