Abstract

This paper discusses two feeders whose apparent characteristics appear similar yet potential response to distributed photovoltaics is drastically different. The feeder´s response to distributed generation is dependent on more than voltage class and loading. Each feeder´s ability to host PV and stay within distribution planning limits is unique. Analysis results of these two feeders will illustrate that a fixed percentage of load, such as 15% of peak, can be a severe under- or over-estimation of a feeder´s true PV hosting capacity.
