摘要：
Power system stability is an important problem for power system operation. Determination of different stability margins can result in the optimum utilization of power system with minimum risk. Voltage stability is an important subset of power system stability. To correctly analyze the voltage stability of a power system, suitable dynamic models are usually required. Therefore, in this paper, the Hopf bifurcation boundary of voltage stability feasible region is analyzed by combination of time domain simulation (TDS), bifurcation theory and modal analysis of dynamic Jacobian matrices of power systems. Effect of different load models, branch contingencies and excitation system parameters on critical eigenvalues and participation factors of system states is evaluated. The test results are given for IEEE14 bus test system. Copyright (C) 2011 Praise Worthy Prize S.r.l. - All rights reserved.
