Validation of Maui PSCAD Model: Motivation, Methodology, and Lessons Learned

As power systems become increasingly dependent on inverter-based resources (IBRs), the dominant physical and control interactions that determine system stability might no longer be accurately captured in positive sequence dynamic simulation tools; electromagnetic transient (EMT) simulations may be needed. This paper describes the process of creating and validating an EMT model of the entire Maui island transmission system in PSCAD software. The model is verified against the utility PSSE model and validated against field data for an event that consisted of a single-phase fault followed by a generation trip. The methodology and lessons learned are summarized.
