Bug Fixes

  • Contingency Analysis: When using Merit Order Open dispatch on an Injection Group that is part of a contingency action, the amount of injection change might not occur correctly if the injection group contains a combination of generators, loads, and switched shunts. The objects that are not needed for dropping are supposed to be ignored, but this was not being done. This has been fixed.
  • Simulator Automation Server (SimAuto): SimAuto functions that take a filtername as input would return data even if the filtername that was specified was not valid. This has been fixed. Now an error message will result and no data will be returned.
  • Transient Stability: Fixed potential initialization problem in the CMPLDW and CMPLDWNF models when FmA + FmB + FmC + FmD + Fel = 1.00000 exactly. This could cause simulator to spit out an error indicating that the summation was > 1.0 when actually it was just exactly equal to 1.0.
