The Quasi Dynamic Simulation can be remotely connected via OPC to (for example) a SCADA system. In this case the current time stamp of the study case may be needed. There are two solutions available:…
Natural oscillations arise from the inherent dynamic interactions between the power system components, whereas forced oscillations are induced by sustained and periodic external inputs. For instance,…
The flag "Direct application of events" is available in the Basic Data page of each Modelica Model (ElmMdl) based on a Modelica Model Type (TypMdl) that uses the "Hybrid" modelling method. The use of…
