Gradual escalation of electric vehicle (EV) penetration in modern power systems requires increasing support for EV charging. This additional demand represents a significant proportion of daily electric load which requires greater or flexible generation and transmission and poses challenges to system security and stability. This paper considers the impact of EV integration on transient stability by using an equivalent model of the Northern Ireland (NI) power system. The paper proposes an AC/DC converter-based EV aggregator model with two typical EV connections. A range of typical faults is investigated and discussed through simulation. The critical clearing time (CCT) and transient stability margin are used to assess transient stability on the NI system. Simulation results indicate that in order to achieve and sustain 2020 EV integration targets and guarantee adequate transient stability, asset support and network reinforcement will be required and these outcomes are described in the paper.
