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 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-infinity-PSS in a multimachine power system.
