Technical FAQs 4

Is a two-stage charging operation mode based on power generation uncertainty?

Establishing a two-stage charging operation mode considering power generation uncertainty. This paper proposes a two-stage bi-layer game charging optimization model based on the background of non-coordination between a network operator (NO), a distributed generation operator (DGO), and a charging agent (CA).

What is a two-stage charging optimization model?

A two-stage charging optimization model considering the uncertainty of wind and solar power was constructed: In the first stage, a DVPBDR model is proposed to pre-optimize the charging load, in order to match the load demand with wind and solar power output as much as possible.

How does virtual charging cost affect EV optimization results?

The virtual charging cost is then used as the optimization objective to create differentiated charging plans for each EV user, thereby minimizing the negative impact of user diversity on optimization results. The approach provides a personalized response strategy reference for EV users with diverse characteristics.

How much does solar energy cost in China?

The generation costs of wind and solar powers are set to be 0.25 CNY/kWh and 0.36 CNY/kWh, and the energy curtailment penalty is set to be 0.7515 CNY/kWh.
