Abstract

A systematic robust decentralised design procedure based on the H _∞-optimisation technique for tuning multiple FACTS devices is presented. The design procedure uses a model-matching robustness formulation and requires the design of a parameter to achieve decentralised control. The approach is used to design damping controllers for an SVC and a TCSC to enhance the damping of the interarea modes in a 3-area 6-machine system. The feedback signals for the controllers are synthesised from the local voltage and current measurements
