... heterogeneity of the systems' structure, identifying the coherency of generators' motion, simplifying the mathematical model of the dynamics of EPSs, assessing their small-signal stability, and selecting the control actions to ensure it. The analysis of sub-Gramians for studying the EPS stability and other new directions in the development of the modal approach are discussed. входит Статья в журнале

DOI: 10.3182/20130619-3-RU-3018.00267 A new mathematical general approach has been suggested to carry out small signals analysis of power systems by computing gramians spectral expansion in time and frequency domains. The gramians expansions are bilinear and quadratic forms for sequences of Faddeev matrices, generated by resolvents of the original matrices in the Lyapunov equation. A new tool for assessment ...
