Aspects of power system modeling, initialization and simulation using the Modelica language

A medium sized power system, with a large number of devices, is fully modeled and simulated in Modelica. For this, new models for electrical components and mathematical blocks were developed in Modelica and the full system topology and parameters were taken from a reference system made in Eurostag. Initialization and time-domain simulations are performed in a Modelica simulation environment and the results obtained for the steady-state and the response to time-events are compared and validated with simulations performed in Eurostag.
