Bug Fixes

  • Transient Stability: For the REPC_A and REPC_B model, added features on August 31, 2021 to handle bad user-input when a branch is NOT specified in the input parameters. When this occurs, then previously we always treated P, Q, and I inputs to the model as 0.0. This was changed to instead use the output of the generator. However, there was a bug when PUFlag<>0 meaning the inputs were assumed on the model MVABase and the inputs were the PUFlag was not being handle properly when the branch was not specified and values of generator output were not scaled by MVABase. This has been fixed.
