Features and Improvements
- Transient Stability: Added ability to read the ESURR1 USRMDL model from a DYR file and convert it to a ESURRY model.
- Transient Stability: Added ability to read the EX21BR USRMDL model from a DYR file and convert it to a AC7B model.
- Contingency Analysis: When using a linear method to solve an injection group ChangeBy or SetTo contingency action, there was an error in the calculation if the change in injection was 0. This error could prevent makeup power from being calculated correctly if there were other actions in the contingency that isolated generators or loads. This has been fixed.
- Contingency Analysis: After defining a contingency analysis CustomMonitor that monitored a field of an actual Contingency object, if the Contingency Combo Analysis was run and CTGComboViolations were created for the CustomMonitor, a problem could occur. The problem was a CTGComboViolation refers to
(1) the Contingency for which the violation occurs
(2) to the object being monitored by the CustomMonitor (which is also a Contingency in this example).
This meant that the CTGComboViolation could reference a Contingency object twice.
When a Contingency was later deleted, errors would occur in Simulator because we were cleaning up references to the deleted Contingency twice and the second time resulted in various bugs. This has been fixed.
