FAST STEADY-STATE STABILITY ASSESSMENT FOR REAL-TIME AND OPERATIONS PLANNING

This paper describes the algorithm and implementation of the Steady-St ate Stability Monitor Prototype - an innovative security application t hat quickly identifies the distance a power system state is from stead y-state instability. Additional information provided by this software includes the: list of generators and synchronous machines that are cri tical for the system's steady-state stability; total amount of MW that can be generated while maintaining a specified stability margin; and the unit MW schedules that maximize the steady-state stability reserve . The method is fast enough to be used both in real-time and as a filt er for operations planning simulations. The software has already passe d common sense validation tests and points to a viable and useful tool .
