New trends such as renewable power; virtual power plants; electric mobility and smart grids raise the importance of electrical power systems. The systems are manifold; including e.g. DC; single- and multiphase AC with fixed and variable frequency. Often times such systems cover other physical domains as well; such as rotational mechanics and thermo-fluid. Required system models range from simple flow calculations of active power to detailed transient and asymmetric studies of three-phase systems. Transformed modal coordinates play an important role for the treatment of three-phase AC systems.
The paper introduces the new Modelica PowerSystems library. It covers arbitrary phase systems in one modeling framework. Besides simple generic models that are valid with all phase systems; also large sets of detailed component models for DC and threephase AC are included. The detailed component models have been ported from the former Spot library to PowerSystems.
The usefulness of the library is shown on behalf of manifold examples and applications carried out so far for power/frequency control; intraday optimization and virtual power plants as well as electrical drive trains of wind turbines.
