Title: | Rapid small-signal stability assessment and enhancement following changes in topology | Authors: | Sarić, Andrija Stankovic A. |
Issue Date: | 1-May-2015 | Journal: | IEEE Transactions on Power Systems | Abstract: | © 1969-2012 IEEE. The paper proposes a scalable and tractable algorithm for dynamic topology optimization of power systems involving changes in branch on/off status, while respecting small-signal stability (SSS) constraints. A procedure for fast updates of the system matrices (in descriptor form) and without additional full matrix inversions is proposed. To additionally reduce the computation time, only critical eigenvalues (right-most or those in a specified damping ratio and frequency range) are calculated. A quadratic optimization approach is proposed for optimized generation re-dispatch to satisfy SSS constraints. The approach is applied to two (medium- and large-scale) real-world test power systems. | URI: | https://open.uns.ac.rs/handle/123456789/4056 | ISSN: | 8858950 | DOI: | 10.1109/TPWRS.2014.2342494 |
