Bug Fixes
- Contingency Analysis: When using linear contingency methods and line outages end up isolating buses, the order of the contingency element definitions could cause slightly different results. This has been fixed.
- General: Fixed access violation error in Anonymize Names in Case.
- Power Flow Solution: Interfaces with open line contingency actions that cause generators, loads, and buses to be isolated will account for these changes in the interface MW flow, shift factors, and PTDFs. Previously only generators and loads that were explicitly modeled as outages in the interface would be handled.
- Security Constrained OPF (SCOPF) Tool: Modified to check the validity of running the SCOPF immediately when attempting to solve an SCOPF. Simulator has long had validity checks to ensuring that areas or superareas existing that were on OPF control and there were generator or load control available for AGC. However, there was not a check immediately to ensure AGC was enabled for the entire case and that Island-based AGC was not enabled. Instead, PowerWorld Simulator would run all the contingencies and then tell there user there was a problem. This has been fixed so the obvious validity checks are done immediately.
- Sensitivity Calculations: Interfaces with open line contingency actions that cause generators, loads, and buses to be isolated will account for these changes in the interface MW flow, shift factors, and PTDFs. Previously only generators and loads that were explicitly modeled as outages in the interface would be handled.
- Time Step Simulation: Bug fix for script command TIMESTEPSaveInputCSV in which the weather values in MPH were not being written.
