Note: All the supported components that exist in XML file will be imported and considered to be in-service. That means for a component that is out-of-service in PowerFactory, the Solver imports its data and treats it as in-service. Thus, it is recommended to remove the data from the input file for the components that are required to be out-of-service during simulation.
