Driving Flexibility: How Incentives Shape EV User Behavior and Reduce Grid Costs - Insights and Implementation from a Discrete Choice Experiment

Exploring Incentives to Enhance EV Flexibility and Reduce Grid Costs Through Discrete Choice Experiments

The presentation focuses on a project exploring how incentives can shape user behavior to enhance grid flexibility and reduce costs, particularly through vehicle-to-grid (V2G) systems. The research uses discrete choice experiments to understand the preferences of electric vehicle users regarding V2G contracts. Key questions include what features users are willing to pay for or require compensation for accepting such contracts, considering factors like income, gender, and whether they have photovoltaic (PV) plants. A significant finding is that cars spend only 3% of their time charging at home despite being parked there often; thus understanding plug-in times is crucial for leveraging flexibility. Different graphs illustrate aggregated car models showing potential cost savings in grid expansion versus increased flexibility costs. Behavioral analysis involves scenarios with households using heat pumps and EVs demonstrating substantial load reduction potentials via V2G utilization—upwards of 32%. Individual characteristics significantly influence contract value perception among different user groups based on driving habits and parking availability. Through surveys involving 15,000 participants across various demographics focusing on realistic decision-making processes rather than traditional polls prone to biases—the study identifies distinct preference clusters: some always opting out while others need strong economic incentives or comfort-focused minimalists requiring tailored offers maximizing regional network benefits by end-project phase leading up stakeholder workshops planned September onwards.
