Distributed solar photovoltaic (PV) generation has begun to impact distribution systems. The impact is unique to individual distribution feeders and is based on certain or all issues ranging from voltage, loading, power quality, protection, and control. The impact distributed PV will have on a specific distribution feeder can only be determined with knowledge of that feeder’s characteristics. These characteristics include but are not limited to load, voltage, regulation, and impedance.

This Technical Update discusses the analysis developed by EPRI to determine distributed PV impact to a specific feeder. The analysis uses a stochastic approach when creating potential PV deployment scenarios. The stochastic nature of the analysis takes into account the uncertainty in the size and location of potentially installed PV systems. Through the examination of issues for thousands of potential scenarios, the feeder impact is used to determine the total amount of PV that is likely to cause an adverse impact to the feeder. This amount of PV is considered the feeder’s hosting capacity, or in other words, the maximum amount of PV that can be accommodated. The feeder modeling, analysis, and evaluation of issues to determine hosting capacity are all discussed in detail in this report.
