I am using DigSilent PowerFactory version 2018 for my research. I found out that DigSilent Powerfactory models that can normally be selected and inserted from general templates into an active project are missing. I do not know what went wrong. The general templates normally contain the following model templates: Battery Systems, Distributed Energy resources, FACTS, Photovoltaic, Plant Controllers, Variable Speed Drives, and Wind Turbine. Please how can I restore them so I can use them in any active project. I await your prompt response. Thanks
