This paper proposes a scalable algorithm to identify and analyze bifurcation points of a large power system model of dynamic voltage instability. Different types of bifurcations are analyzed, such as: saddle-node (fold), Hopf, singularity-induced, and limit-induced bifurcations. The interval bisection based algorithm is proposed for determination of the steady-state equilibrium point. The proposed...
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...
The paper explores the influence of topology changes (due to the change in transmission branch on/off status) and injection perturbations (due to economic load/generation redispatching) on the eigenvalue sensitivity of the power system dynamic model. These control actions are analyzed as part of dynamic transmission topology control. An algorithm for fast updates of the system matrices (in descriptor...
