Abstract
In Norway there is an increased interest in utilizing photovoltaic generation of electricity (PV) in building installations. As many parts of the LV distribution system in Norway are rather weak, large influx of PV might introduce both voltage quality problems as well as feeder overloads. As the observability of the LV distribution systems will increase due to the deployment of smart meters and new sensors/instrumentation in MV/LV substations, these technologies can be applied in smart house and micro grids concepts to maximize PV hosting capacities and to reduce the need for traditional grid measures (lines/cables, increased transformer ratings etc.). A set of use cases has been developed for this purpose and their technical and economic potential have been analysed by a set of simulation models as presented in this paper.
