#SESAAU2020
Independent planning vs. Integrated planning [1]
Interregional energy cooperation
• Make development plans together
to seek mutual benefits
• Allow cross-regional energy
interaction
One energy system model
• Integrated model for BTH region
Beijing
Tianjin Hebei
Non-cooperative
• Draw up energy development plan
locally
• Operate energy system
independently
Three energy system models

Conclusions
The vehicle electrification could contribute greatly to
sustainable energy transition without any significant cost
increase
Interregional energy cooperation and smart charge should be
given priority
