1 Introduction. There is a general consensus that the large-scale deployment of electric vehicles (EVs) and distributed renewable energy resources can effectively reduce dependence on fossil fuels in the transport sector, thereby reducing carbon emissions (Borén et al., 2017; Khan et al., 2019).The number of EVs is growing by the day, and EVs charging is
Great research effort has been devoted to leveraging energy storage equipment to assist demand response management (Cui et al., 2017; Tang et al., 2019). For instance, it has to be mentioned that the unrestricted deployment of electrical energy storage devices will bring great economic burden, which is impractical.
In addition, installing energy storage systems (ESS) in a GCS is recently considered as one promising solution to accommodate the intermittent renewable energy sources and uncertain EV charging demand .For example, it is pointed out in that the integration of PV panels and ESS in charging stations can relieve the pressure on the distribution network
