    Abstract

    Based on conventional car driving patterns, it has been recognized that typically a car remains stationary for 95% of the time, only being driven on the road for the remaining 5% of that time on average. This gives the system operator opportunities to utilize future EV charging as system reserve demand in order to provide system control, such as frequency response. In this paper, a next generation power system with high penetration of renewables represents the future power grid in Great Britain. Three charging schemes for EVs are presented in order to illustrate their potential as responsive demand for power system control. A case study was undertaken for the year 2020. System frequency stability tests have been performed with shedding EV fleet charging.
