Aiming at the problems of low new energy consumption rate

increased EV charging network loss

and distribution network node heavy load under the disordered charging of large-scale electric vehicles (EVs)

a proactive EV spatiotemporal optimal dispatch strategy based on the guidance of equivalent load real-time tariff and node real-time tariff is proposed. First

equivalent load real-time tariff is developed from base load

wind power

and photovoltaic power to guide the charging and discharging of Type Ⅰ EV clusters responsive to active EVs in the time dimension. Second

based on the equivalent load real-time tariff

the node real-time tariff is formulated by considering the node network loss sensitivity and the node load ratio to guide the Type Ⅱ EV users

who are also responsive in the spatial dimension

to select the charging and discharging nodes. A distributed grid in Jiangsu Province containing wind and solar energy is used as a simulation. This strategy can realize the stepwise utilization of EV clusters

which is of great significance to enhancing the rate of new energy consumption

reducing the charging network loss

and ensuring the security of the distribution network.
