Mathematical modeling is a key step in the analysis of power system stability. In view of model accuracy, this process should include all relevant details that affect the transient behavior of the power system. To this aim, an extension of the generator subsystem model is introduced in OpenModelica by adding a new turbine-governor model. Taking advantage of the multi-domain modeling property of OpenModelica, two libraries are coupled to interconnect the mechanical and electrical domains of the generator subsystem. The new generator subsystem is tested using the standard IEEE 9-Bus test feeder and the simulation results in OpenModelica are furthermore compared to respective results in DIgSILENT PowerFactory. The new generator subsystem model is integrated into the validated 20 kV power grid model of KIT-Campus North and respective results are presented for abrupt load changes.
