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.
