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).
- 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.
