Research on the coordinated scheduling strategy of multilevel charging and discharging resources under heavy load scenario in station area

The large-scale integration of electric vehicles poses significant challenges to the safe and stable operation of distribution network substations. This article analyzes the impact of disorderly charging and discharging of electric vehicles on heavy overload in the substation area. Propose a multi-level charging and discharging resource coordination and scheduling strategy of "pile station network". And build a multi-level coordination and optimization framework for charging and discharging resources. The case analysis shows that the model and algorithm proposed in this paper can effectively alleviate the problem of heavy overload in the substation caused by disordered charging and discharging.
