Monte Carlo Simulation for Assessing the Voltage Level and Losses with Photovoltaic and Electric Vehicle in Low Voltage Network

Abstract

Livelab from Alliander is a program which started to measure electrical and power quality data in the Dutch distribution network since 2013. This paper presents a methodology to generate the residential load profiles by cumulative distribution function (CDF) based on Livelab measured data, then applying Monte Carlo simulation method, a statistic three phase Load Flow program is developed in order to investigate the voltage level and network losses (harmonic loss is considered) of a typical low voltage (LV) network with the consideration of variable loads and random locations. Then, the prospective impact to voltage level and losses due to the grid connected photovoltaic power generation systems (PV) and electrical vehicles (EV) are discussed, Monte Carlo simulations are done with the different penetration rates of PV and EV, maximum capacity of grid-connected PVs and EVs can be estimated and the possible network losses are calculated.
