Bug Fixes

  • Power Flow Solution: When loading a case as an AUX file and then immediately solving the case using automatic generation control, it was possible to see the slack bus generator move, the system response, and then everything move back to where they started. This was unique to an AUX file when solving with AGC immediately. If loading an AUX file and solving the power flow with AGC off initially and then solving with AGC this did not occur.
  • Transient Stability: When using the plotting tool to "Save Selected Plot Data to a Comtrade" format, PlayIn data shown on the plot should not be stored and should be ignored. It was however not being ignored and causing an access violation. This has been fixed so it is properly ignored. PlayIn data is not on the same time-points as other data, so it is not properly saved to a Comtrade format.
