摘要

Eigenanalysis and frequency domain techniques are used for selection of the best sites for application of controllers in multivariable power systems and to design robust H_∞ controllers, which are constrained to be decentralized with reduced order and fixed structure. Parameters of the controllers are tuned by using a reliable optimization method to result into a robust control in damping of the critical oscillation modes. Interactions among controllers are analyzed. A good coordination of control is achieved by simultaneous design and application of all controllers in the selected sites. The proposed techniques are applied to design H_∞-PSS in a multimachine power system.
