    TSAT Model Quality Test (MQT) Case Preparation Tool January 2024 -The TSAT Model Quality Test (MQT) Case Preparation tool is available on request (contact dsainfo@powertechlabs.com), free of charge for active licensed TSAT/PSAT users.This add-on module will allow for automated preparation of TSAT cases to streamline the evaluation of TSAT-compatible plant models in accordance with ERCOT Dynamic Model Submittal Guideline with additional customizations available (similar to the tool, DMVIEW as prepared by ERCOT).

    The TSAT MQT Prep add-on module will automatically prepare flat run, HVRT, LVRT, frequency variation, and variable SCR tests according to the configuration and input data provided, with support for both TSAT Equipment Name and Bus Number formats. Where applicable, automated powerflow variations are supported or data can be manually specified for each test case. The tool requires recent versions of both PSAT and TSAT in order to function.

    Powertech would like to credit ERCOT’s Operational Stability team (Dr. Yunzhi Cheng, Dr. Hamzeh Davarikia, and Dr. Mehdi Daryabak) for their efforts in refining this add-on module to meet requirements.
