Analysis of Future Loading Scenarios in a Norwegian LV Network

Abstract

This paper identifies the effect of Electric vehicles (EVs) and solar panels/photovoltaic (PVs) on the distribution grid with and without the use of demand response. A method to generate realistic profiles of EVs and PVs based on statistical data is presented. The paper documents the impacts of EVs and PVs on a selected Norwegian LV distribution network by using up-to-date scenarios of the loads and actual network and household load data. The simulation study reveals that undervoltage problem caused by EV is considerably more likely than overvoltage problem caused by increased PV integration. In another dimension, flexibility resources such as shiftable loads from household appliances showed greater potential to solve overvoltage problems due to PV integration than undervoltage problems due to increased EV integration. © 2019 IEEE.
