Modelling and Simulation of a New Power Delivery in the North of Iceland. Tien Thanh Nguyen Master's thesis, University of South-Eastern Norway, Porsgrunn, May, 2018. abstract bibtex A former assessment report conducted by Verkís using the proprietary simulation tool DIgSILENT PowerFactory is now implemented in Dymola with the OpenIPSL library. The OpenIPSL is a power system component library started as a successor from the iPSL library in the iTesla project. It has proven to be suitable to develop and perform power system phasor time domain simulations. The main goal of this thesis is to perform initialisation and time domain simulation in Dymola. The results obtained in steady state will be compared, and validated with the power flow simulations performed in the DIgSILENT PowerFactory. The time domain simulation in Dymola provided the expected results compared with PowerFactory power flow calculation, with a slightly difference in voltage level and reactive power dispatch. However, power system without a shunt capacitance is not recommended because of the reactive power demand cannot be achieved, and the voltage limits has been violated. The additional time domain simulation to analyse the dynamic response of the power system did not yield the expected results. The main source to this is the time domain simulation that has not been fully analysed in the PowerFactory to obtain the correct implementation in Dymola, and is therefore restrained to as future work. Otherwise, the short- circuit analysis did show great similarities. Above all, the Modelica language in modelling of power system is reliable if the correct implementation is performed. It can highly be recommended because Modelica language is equation based modelling, and can describe the exact physical behaviour of a component model independently of the software. It provides a great advantage in sharing consistent models between different simulation tools supporting Modelica.
