    Abstract

    With increasing demand for high-powered fast chargers,
    the impact of connecting a multi-megawatt charging
    station to medium voltage networks should be evaluated
    to ensure that the safe and reliable operation of the
    network is not compromised. This paper assesses the
    impact of integrating multi-megawatt medium voltage
    fast charging stations on network stability based on the
    outcome of quasi-dynamic load flow simulations. Grid
    voltage, line loading, and power losses are used as the
    key performance indices. Additionally, various scalability
    scenarios have been investigated to evaluate the impact
    of large-scale rollout. Finally, adequate system sizing,
    alongside an evaluation as to whether on-site solar
    photovoltaic and battery energy storage system
    combinations can be used to provide grid support and
    foster zero-emission charging is done. The results show
    that installing a multimegawatt charging station on the
    medium voltage network will have little or no impact on
    the stable operation of the network. Additionally, the
    scalability scenarios show that large-scale rollout is
    possible, however, it is limited by the capacity of the
    network. Finally, self-sufficiency and peak shaving
    applications can be used to reduce CO2 emissions and
    provide grid support mechanisms, though this may not be
    economically feasible.
