Software Patches

Features and Improvements

  • Transient Stability: Modified the validation check on synchronous machines to ensure that Xqpp is not too big. Previously we enforced (Xqpp <= 1.1Xdpp), but have changed this to (Xqpp <= 1.5*Xdpp).
  • Bug Fixes

    • Available Transfer Capability (ATC) Tool: Fixed bug introduced in the June 18 patch when reading the concise WECC RAS format that contained Model Expressions. The field for "Expression" was not being properly read.
