Abstract
The use of fossil fuels has significant effects on climate change due to greenhouse gas emissions and various environmental pollutions. Thus, many renewable energies have been introduced and are regarded to substitute for fossil fuels in multiple industries, particularly in the transportation industry. In order to encourage the electric vehicles uptake, this article focuses on the location and capacity allocation model for the electric vehicle charging stations’ network. The practical approach of this study starts with the charging demand estimation according to the population density to determine the number of charging stations. And then, based on the continuous location model and other relevant methods, the location and capacity of charging stations are determined. After that, the construction order of all EVCSs and cost analysis are discussed. The computational experiment is presented through employing the real-world data of DH postcode area in the UK. The result shows the final location and the construction order of EVCSs' network planning in a specific area.
The primary concern of this study is to provide a comprehensive mathematical model which is essential to determine the optimal locations of EVCSs in the UK. There are three aspects to consider particularly:
- How much demand for EV charging in the specific regions?
- Where should EVCS infrastructure be placed?
- How to determine the optimal capacity and location of EVCS network, taking into consideration financial costs like investment, capital, operation and maintenance?
- How to identify the order in which EVCSs should be built in long-term planning?
Regarding these principles, the overview of this project will be clarified as
- Which methodology can be used to develop the mathematical model and solve the solution(s) for the particular case study?
- What recommendation can be suggested to develop EVCS infrastructures in the UK?
In order to address the electric vehicle charging infrastructure challenge which currently inhibits the uptake of electric vehicles in UK, the 'Scaling On-Street Charging Infrastructure Project' (SOSCI) has been launched, which plans to deliver pilot EV charging point installations to work towards the vision for the 8 million homes without off-street parking to be within 5-minute-walk of an EV charging station. The aims of the study are to develop location-allocation models to support the deployment of Electric Vehicle Charging Stations (EVCSs) in the UK. Then, the practical approach can be applied and verified by the real input data of the DH postcode area to show precise results, the result's discussion, and recommendations.
