Overvoltage Analysis in Norwegian Distribution Test Bench Grid with High PV Penetration Ludvig Syrén, Erik Jonasson, Samuel Forsberg, Janaína Gonçalves de Oliveira, Juan de Santiago

Abstract

This article presents a literature review on the most relevant quality parameters for hosting capacity in the Nordic context. A distribution grid from Norway is presented in detail to be established as a test bench for further studies. The grid covers different voltage levels, from 47 to 0.4 kV.
A hosting capacity analysis is performed on the proposed grid. The solar PV hosting capacity of the proposed grid has been estimated for a PV penetration of about 160% when voltage limits are considered. It was determined that the transformer and cable ratings are the main concerns in determining the hosting capacity, rather than the voltage deviations. This is in line with the findings of the literature review. We argue that this is the case for most grids in the Nordic.
