Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE credits
Recent eorts of collaboration between the European transmission system operators have led to
an increased interest in common research projects concerning power system analysis. The iTesla
project is an example of European collaboration that focus on developing common tools for the
simulation and analysis of large scale power systems. The work carried out during the thesis is a
part of the iTesla project in which Modelica has been selected as a common simulation platform.
The work encompasses the development of Modelica classes for power grid components used in
dierent Norwegian grid dynamic Models.
The simulation platform PSS/E is used as a reference software for the developed power system
models. In this thesis power system models have been implemented in Modelica. The perfor-
mance of these Modelica classes have been validated through comparing between the behavior of
the developed and reference models in dynamic simulations. The validation process simulating
several small scale power system models and a subset of the Norwegian grid model that have been
identically implemented in both simulation platforms. The results from the dynamic simulation
under dierent perturbation have been compared in accuracy to validate the work.
