Objectives and research topics
Project main objectives
Assess the values of EV services in DK, UK and Japan, by using real EV driving data.
Disseminate V2G applications and best practices in Europe and in Japan.
Establish tight collaboration with the research area of a large car manufacturer.
Vehicle manufacturer (such as Nissan) will use the project outcome to improve future vehicle designs in order to make them more “grid proactive”.
Build up on the experience on Bornholm test case and contribute to enrich it.
Derive guidelines for coordinating system wide services provided locally: Distribution System Operator (DSO) vs Transmission System Operator (TSO).
Test whether EVs can help supporting Bornholm power system (balancing mainly).
Research topics and questions
The following research questions support the techno-economical investigations
1. DSO vs TSO coordination and grid modeling
Can a large set of EVs contribute to balance an islanded power system without inducing local grid issues?
What specific mechanisms will allow EVs to include local constrains while providing system (island)-wide services: that means DSO/TSO coordination?
What are the specific synergies with wind integration and can EVs increase the amount of renewables supported in an “islanded” scenario?
Will Bornholm power system safely and securely supply a 100% EV penetration scenario and which guidelines could be provided to the local DSO (Bornholms Energi & Forsyning) in order to achieve step by step a 100% scenario?
2. EV aggregating functions
Contract phase: for how long, how large, and how fast the aggregated power of EV fleet should be ready on a daily, weekly or monthly basis when contracting with the system operator?
Real time operation phase: how to ensure the control signal given by the system operator will be strictly followed?
How much do a specific driving pattern and the energy capacity of the EV affect the control method when providing the ancillary services?
3. Services economic and technical analysis
How much the degradation of the battery, while providing system services, affects the service profitability?
What is the trade-off between using the fleet for ancillary service (AS) profit optimization and using the fleet for renewable/operational support?
What is the saturation level of the ancillary service market in term of EV population?
