| Summary: | Electric vehicles (EVs) have been rapidly developed during the last few years due to the
low-carbon industry and smart grid initiatives. Meanwhile, the impact of
large-scale EVs' integration on the reliability and safety of power grids is
becoming increasingly prominent. To address and solve these problems, challenges
on EV charging control have been presented. Besides, the EV charging load
modelling with improved accuracy and rationality is required. To investigate the
influencing factors of EV charging load, this survey summarises the existing EV
charging load modelling methods. In addition, a new research framework for a
scale EV evolution model of charging load is proposed, with an emphasis on
reducing the deficiencies of the existing research in dealing with the EV scale
development. Moreover, the future research prospect of EV charging load
modelling on power system planning, operation, and market design has also been
discussed.
