Abstract :
The authors describe algorithms suited to the efficient calculation of both proper and nonproper transfer function zeros of linearized dynamic models for large interconnected power systems. They also described an improvement to the well-known AESOPS algorithm, formulating it as an exact transfer function zero finding problem which was efficiently solved by a Newton-Raphson iterative scheme. Large power system results are presented
