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

This paper describes the algorithm and implementation of the Steady-State Stability Monitor Prototype - an innovative security application that quickly identifies the distance a power system state is from steady-state instability. Additional information provided by this software includes the: list of generators and synchronous machines that are critical 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 filter for operations planning simulations. The software has already passed common sense validation tests and points to a viable and useful tool.
