Abstract :
A dynamic voltage stability analysis of a single-machine constant-power-load system is presented. The system model includes only the machine voltage variables. A key factor in the analysis is the variation of the conditioning of the network Jacobian matrix with respect to the constant power load demand and the machine voltage source. It is shown that a dynamic instability phenomenon arises when the Jacobian matrix is ill-conditioned. The results presented include eigenvalue analysis, control parameter sensitivity analysis, and nonlinear voltage collapse simulations
