A New Stabiliser Design Technique for Multimachine Power Systems

Abstract

This paper presents a new method of designing decentralised stabilisers for improved dynamic performance of multimachine power systems. The method determines the parameters of all stabilisers in the system such that some or all of its mechanical modes eigenvalues have desired locations in the complex plane. The proposed algorithm is general, effective and simple to apply. This is illustrated through three numerical examples including a three-machine and nine-machine infinite bus power systems, and with different degrees of system modelling.
