Accurate models are essential for studying FIDVR events, and much work has been done to develop and refine successful models. Key activities in this area include:
- In 2011, John Undrill developed a point-on-wave single-phase motor model, which provided insight into sensitivity of motor behavior to the phase-of-supply voltage at the instant a voltage disturbance is initiated.
- In 2012, Schweitzer Engineering Lab incorporated the motor model into a "real-time" digital electric system simulator (RTDS) to analyze a full population of A/C units within a distribution feeder.
- In 2013, Arizona State University (ASU) incorporated the motor model into the PSCAD simulation program.
