An investigation into the improvement of the Westfjords’ power system was completed. There are plans to build a new hydropower plant, Hvalárvirkjun, in the Westfjords of Iceland which could provide the region with more reliability, as well as increase the potential load that the Westfjords’ power system can handle. In partnership with both Landsnet and Verkis, this thesis demonstrates the use of multiple industry-accepted tests to determine a suitable connection point for Hvalárvirkjun. To determine the best possible connection point, tests based on voltage profile, line loading, reliability, and cost were performed. First, a steady state power flow analysis was completed to determine both line loading and the voltage levels at each bus for each option. Furthermore, a N-1 contingency analysis combined with a probabilistic reliability assessment was used to determine the reliability of each option. Finally, a project cost and social cost was determined to help evaluate the potential for each connection point. The original system was also analyzed and presented for a comparison point. Combining the results from all of the tests, a final recommendation was made which includes three of the ten different options, where two recommendations show a 66 kV connection directly to Ísafjörður in the northern ring and the other advises a 132 kV connection to Mjólká. Future recommendations include the use of this thesis structure in order to expand on the reliability and cost functions and provide a more exhaustive study of the three connection points. Endurbætur á flutningskerfis Vestfjarða hefur verið rannsakað. Áætlað er að byggja nýja vatnsaflsvirkjun á Hvalá á Vestfjörðum sem mun bæta áreiðanleika kerfisins og auka álagsgetu þess. Sannreyndar prófanir og greiningar voru framkvæmdar til að ákvarða tengipunkt Hvalárvirkjunar við flutningskerfið. Þær prófanir sem að voru framkvæmdar á hugsanlegum tengipunktum, voru byggðar á spennuprófíl og þéttavirkni línu. Nokkrar tillögur komu til greina og voru prófanir og greiningar ...
