Bug Fixes

  • File Formats: Customers have reported that renewable dynamic machine models do not function when read from DYR models in other software if the power flow generator model flag WMOD do not set to a 1. When writing out a RAW file, if the WindControlMode in PowerWorld is set to none, then the generator WMOD field in the RAW file will be determined by the type of dynamic machine model used for the generator. For machine models that are for renewable machines (WT1G, WT2G, WT3G, WT4G, REGC*, PVD1, PV1G, and so on), the WMOD will be written as a 1 and for other generators the value will be a 0.
