Abstract: With the large-scale integration of electric vehicles into the power grid, the disorderly charging behavior of users will have a negative impact on the safety and economy of the power system. This paper extractes the charging load characteristics of different types of electric vehicles, and the interaction and influence of cluster electric vehicles and power grid in the direction of system stability are analyzed.The simulation results show that through the cluster regulation of flexible resources such as charging time and charging power of electric vehicles, the schedulable characteristics of electric vehicle load can be effectively utilized, more demand-side potential can be brought into play, and the goal of peak cut on the demand side load can be achieved.
Key words: electric vehicle; requirement response; power system; load characteristic
