Equation-free technique is based on multiscale approach which operates on fine scale to elucidate dynamics of coarse scale. It has been used for years in fields such as physics, chemical engineering, mathematics and biology. With increasing complexity of power system component models, the analysis of system level behaviour is uncertain or is computationally prohibitive by conventional methods. This...
This paper proposes a tractable and scalable algorithm to identify and analyze bifurcation points of a large-scale power system model, which are directly related to dynamic voltage instability problems. Different types of bifurcations are analyzed, including: saddle-node (fold), Hopf, singularity-induced and limit-induced. An algorithm that combines optimization and predictor-corrector procedure is...
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...
