Stability screening methods like short-circuit ratio (SCR) and its variants have been a mainstay of the industry for decades for their simplicity. As we move into higher penetrations of IBR with different performance characteristics, the SCR methods become an increasingly unreliable indicator of stability. On the other hand, time-domain simulations can have high accuracy, but are onerous to set up and run. This webinar shares work on the Dynamic Impedance Method that bridges the gap, addressing the shortfalls of SCR methods while retaining scale for huge bulk power system models with many thousands of resources and buses. The approach is much simpler, and faster to use than phasor domain and EMT simulations.
