Double singularity-induced bifurcation points and singular Hopf bifurcations

摘要

The singularity-induced bifurcation and singular Hopf bifurcation theorems and the degeneracies that arise when Newton's laws are coupled to Kirchhoff's laws are explored. Such models are used in the electrical engineering Literature to describe electrical power systems and they can taken the form of either an Index-1 differential-algebraic equation (DAE) or a singularly perturbed ordinary Differential equation (ODE). As a consequence of the debate in the engineering Literature as to which class of system is the 'true' representation f power systems, A discussion is included of the consequences of the power engineer's 'load-flow Singularity' for both ODE and DAE..
