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