SPP Model Quality Tests
The SPP model quality tests for inverter-based plants, benchmarked across PSCAD, PSS/E and TSAT.
About this module
What this module covers.
SPP's Generating Facilities Modeling Requirements Manual, filed with the Federal Energy Regulatory Commission (FERC) in docket ER26-3625, sets model quality tests (MQT) for inverter-based resources (IBRs) seeking interconnection. This module conducts the required SPP MQT studies for the plants you select to validate your dynamic simulation models against SPP's performance criteria, benchmarked across PSCAD, PSS/E, and TSAT.
Module: 073
Kind: Modeling studies
Governing body: SPP
Applies to: Before and after commercial operation
Typical time: Two to three weeks, all in, including your review
Dashboard capabilities
- MQT workspace in the GridStrong Dashboard
- Model Workspace Management across PSCAD, PSS/E, and TSAT
- PSCAD, PSS/E, and TSAT Simulations
- Plant Evidence Locker for source documentation
- Automated MQT report generation
Support services
What GridStrong does inside this module.
- Perform all required SPP Model Quality Tests (18 tests; full list below).
- Benchmark results across PSCAD, PSS/E, and TSAT models.
- Coordinate with original equipment manufacturers (OEMs) on modeling deficiencies identified during testing.
- Prepare the MQT report for your submission to SPP.
Tests: Steady state / flat
- No Disturbance (Pmax, Qmax)
- No Disturbance (Pmax, Qmin)
Tests: Faults
- Bolted 3-phase-to-ground fault, 10 cycles (Pmax, Qmax)
- Bolted 1-phase-to-ground fault, 10 cycles (Pmax)
- Short Circuit Test (short circuit ratio ramp 20 to 1 plus bolted fault)
Tests: Small disturbances
- Small Voltage Disturbance (Pmax)
- Small Frequency Disturbance Up (Pmax)
- Small Frequency Disturbance Down (50% Pmax, two headroom cases)
Tests: Ride-through
- High / Low Voltage Ride-Through (Pmax)
- High Frequency Ride-Through (Pmax)
- Low Frequency Ride-Through (50% Pmax, headroom)
Tests: Protection
- High / Low Voltage Protection (1.5 pu / 0.0 pu, 5 s)
- High / Low Frequency Protection (70 Hz / 50 Hz, 5 s)
Tests: Other
- Grid Phase Angle Up (+25 deg, Pmax)
Final deliverables
- SPP MQT report including results from all required tests.
- Updated PSCAD, PSS/E, and TSAT simulation models where applicable (charged under the related modules).
What we need from you
- Latest PSCAD, PSS/E, and TSAT simulation models including collector system, main power transformer, power plant controller, and all necessary control and protection.
- Single-line diagram of the plant.
- User manuals and OEM documentation.
Assumptions and considerations
How the scope is bounded.
- Required tier only; the supplemental SPP tests that may be demanded before commercial operation are out of scope for this module.
- The test list follows the manual as filed in ER26-3625, as of October 29, 2026; test names and requirement numbers may change when the filed revisions take effect.
- You supply all required models and site documentation.
