Behaviour Analysis of Electrical Vehicle Flexibility Based on Large-Scale Charging Data

The massive deployment of electrical vehicles (EV) creates new challenges and some opportunities for power systems. This paper focuses on the potential of EV charging stations to provide flexibility for electrical grids. Since there is no concrete definition for flexibility in power systems, this paper first looks at the market opportunity for flexibility and then proposes a method to calculate the flexibility of EV based on the market definition. Then, the flexibility of EV is derived from data collected from charging stations in the Helsinki area between 2015 and 2018.
