Situation Awareness of Electric Vehicle Charging Load Based on Random Forest Algorithm

Table 1

Classification rule of situation levels.

Situation levels	Situational range	Regional status	Detailed description
1		Unobstructed	Resources can fully meet the charging needs of electric vehicles
2		Basically unobstructed	The resources can basically meet the charging needs of electric vehicles, and occasionally, there is insufficient supply
3		Light congestion	Under normal circumstances, the resources can meet the charging needs of electric vehicles, but sometimes there will be insufficient supply
4		Moderate congestion	The resources can meet the charging needs of electric vehicles in most cases
5		Serious congestion	Resources are basically unable to meet the needs of electric vehicles and other loads
