Fast Analysis of Stability Using the Extended Equal Area Criterion & Simulation Technologies (FASTEST)

Based on EEAC quantification theory, this software can fully and rapidly quantitatively evaluate the transient safety and stability of power angle, voltage and frequency as well as the dynamic damping safety in the power grid. In addition, it also can analyze the static safety, static voltage stability, medium-term voltage stability and small disturbance stability, automatically calculate the emergency control optimization strategy on the second defense line, and optimize and set the low-frequency low-voltage load shedding parameters.
