Electrical Vehicle Charging Station Placement
Considering V2G in Multi-Energy System
Authors: Chuan Li, Daniele Carta, Andrea Benigni
The paper researches the best way to place electric vehicle (EV) charging stations in future energy systems.
The aim of the project includes:
- Planning locations, sizes, and types of charging stations
- Explore vehicle-to-grid (V2G) technology, helping balance energy supply and demand
- Find the cost-effective solution while ensuring energy systems and charging stations operate smoothly.
Electric Vehicle charging stations with vehicle-to-grid technology in energy systems.
How is it researched?
The research uses a method called two-stage stochastic programming with uncertain models. It works in two stages:
- Stage 1: The researchers decide on possible locations, numbers, and types of charging stations based on initial plans and V2G technology.
- Stage 2: They test these decisions by simulating different scenarios. For example, what if it’s a sunny day with lots of solar power, or a cloudy day with high EV demand?
This approach helps them account for random factors like weather, energy prices, and people’s driving habits, thereby find the best overall plan.

What is the benefit for society?
- Cost Savings: By placing charging stations with V2G, it reduces costs for both EV owners (cheaper charging) and energy providers (less waste).
- Better Energy Use: It makes the energy system more efficient, reducing stress and overloads, especially when lots of EVs are charging at once.
- More Renewable Energy: The V2G technology and smart placement help integrate renewable sources like wind and solar, cutting down reliance on fossil fuels and reducing greenhouse gas emissions.
Overall, this study lead to a cleaner and reliable energy system that supports the long-term climate goals.
