Conclusions HTS applications in power systems will be more competitive in the future Time series analysis provides a clearer overview about the implications of the integration of HTS cables into distribution grids as it takes into consideration the fluctuations of the renewable energy generation and load profiles. The ability of the HTS cables in decreasing the total energy loss of the grid depends on different factors such as the proposed location, and the loading state. 17.06.2015 Hemdan HTS Cable Integration into Rural Networks with Renewable Energy Resources Seite 34
