Bug Fixes
- Power Flow Solution: Fixed an issue with the SVC solution. When the SVC was hitting MVARS or Reactive current limits it was oscillating a lot causing to iterate the voltage loop until the limit. Now it does not oscillate.
- Transient Stability: Fixed error in handling transient stability DC line equations when the voltage controlling converter changed during a stability run because the original voltage controlling converter was unable to maintain the voltage schedule.
- Transient Stability: Fixed error in the PDCI transient stability models that occurs for the south-north flow.
- User Interface Dialogs: Previously after defining a piece-wise linear cost curve for a generator it was difficult to delete the points in the curves globally. Simulator would attempt to always maintain one MW/Price point in the curve to be "helpful" to the user. While this prevents the erroneous input information of specifying a CostModel of Linear without specifying points on the curve it was more annoying than helpful. The user interface has been modified to allow a user to delete all price points now and the OPF and Economic Dispatch algorithms have been modified to capture this situation and ignore generators specified as a Linear model but without a curve - treating this the same as a cost model of None. The easiest place to delete all points is in the Model Explorer under Optimal Power FlowBidsGenerator Bid Curves. Alternatively it can be done running the script command Delete(GenBid);
