Bug Fixes

  • Power Flow Solution: Fixed a very obscure bug when using Island-Based AGC control with a larger convergence tolerance (Tolerance > 0.5 MW). This would not occur with Area/SuperArea control but only with Island-Based AGC control in the power flow solution. The bug could cause the resulting power flow solution to not properly enforce the AGC tolerance and thus have the slack bus move more than it would have otherwise moved.
  • Transient Stability: Fixed access violation that could occur when a ATRRelay triggers the trip of a generator.
