Abstract

Discusses an iterative method for designing power swing damping controllers. The method solves directly for a low-order robust controller, and if convergence is achieved, results in the closed-loop system satisfying a frequency-domain bound. It is based on the optimization of dynamic systems with linear matrix inequalities as the design constraints. Controller constraints such as decentralization and positive realness can also be included in the design. The proposed method is used to design a power system stabilizer for a single-machine infinite-bus system and a decentralized two-channel series and shunt capacitor damping controller for a three-area system
