Abstract :
This paper presents a concept of enhancing the photovoltaic (PV) power generation hosting capacity of distribution networks. Distribution network serving electrical energy to farm settlements was selected as an example for their large roof area available for PV installation. Further, they are characterized by long radial feeders. Such feeders suffer from voltage rise and transformer overloading problems as the total number and capacity of the PV installations increase. The distribution network can be augmented by dc distribution links with power electronic converter interfaces to the traditional ac distribution systems. It is shown here that the dc links can be used to interconnect the different radial feeders and the excess power thus could be transferred to the nearby industrial load-center.
