Locating unstable equilibrium points for power-system transient-stability analysis
Technical Report
·
OSTI ID:6356934
This work analyzes several approximate methods for efficiently locating unstable equilibrium points (u.e.p.'s) of the structure preserving model for transient stability analysis as developed by Bergen and Hill. The role of these u.e.p.'s in predicting the region of attraction for the post fault stable equilibrium points via Lyapunov techniques is discussed. The sensitivity of Lyapunov energy to error in the approximate u.e.p.'s is analyzed. The approximations are applied to a simple six bus, four generator system, with numerical results of the various approaches contrasted.
