Bug Fixes

  • Transient Stability: If a fixed switched shunt is assigned to a transient stability model it is allowed to move based on the model. This might require that shunt blocks be defined. Shunt blocks are not always defined for a fixed shunt. During a transient stability run if a fixed shunt has no blocks defined, has a non-zero nominal Mvar output, and zero Min Mvar and Max Mvar, a single block of the initial nominal Mvar output will be created and the limits will be set based on the nominal Mvar output.
  • Transient Stability: Fixed a bug with initializing the GroupMSS transient stability injection group model that could result in switched shunts not moving even though they should based on the enabling criteria and voltage conditions.
