Abstract

Multi‐year planning of LV networks with EVs accounting for customers, emissions and techno‐economics aspects: A practical and scalable approach

Highlights

The need to decarbonize the transport sector combined with the falling prices of electric vehicles (EVs) are paving the way for the widespread adoption of the technology
To address the aforementioned gaps in the literature, this paper presents the following contributions: (i) A practical and scalable, stochastic, progressive multiyear planning methodology that considers technical, customer, economic and environmental aspects to make holistic planning decisions for existing low voltage (LV) networks to accommodate EVs in the coming years
The investigated planning alternatives have been designed to mitigate asset overloads and voltage drops that might occur on LV networks due to EVs

Summary

Introduction

The need to decarbonize the transport sector combined with the falling prices of electric vehicles (EVs) are paving the way for the widespread adoption of the technology. For Distribution Network Operators (DNOs), the expected coincidence between EV charging and domestic demand raises concerns as it will increase evening peaks [1, 2]. This means that, in the coming decades, investments in existing distribution networks will be required to mitigate EV impacts such as thermal overloads and substantial voltage drops. From a distribution expansion planning perspective, DNOs will, in practice, have to first forecast the horizon and corresponding EV uptake They will assess the ability of existing LV feeders to cope with the future EV demand via technical aspects such as asset utilization and voltage drops [5].
