6 FAQs about [Charging and discharging price difference of independent energy storage projects]

Should energy storage charge and discharge strategies be adjusted?

Shandong, Gansu and other regions implemented complete price adjustments for all TOU periods. While the widening of the peak and off-peak price difference is beneficial to behind-the-meter energy storage applications, energy storage charge and discharge strategies must also be adjusted to adapt to the changes to the peak and off-peak period.

What is the charging–discharging method?

Technically, the charging–discharging method is dependent on the location of the majority of parked EVs, and the load demand. Fig. 1 illustrates a general EV charging–discharging scheme with both controlled and uncontrolled charging.

Are charging and discharging the same thing?

In the context of a block-chain-based tool, charging and discharging are two faces of the same coin, between which the tool maintains a balance. It is to be hoped that more people will eventually be convinced to charge their vehicles using clean energy.

What is intelligent charging –discharging?

Intelligent charging–discharging refers to a system whereby a data connection is shared between an EV and a charging station, and the charging station is connected to a transmission/distribution system operator.

Why is the integrated photovoltaic-energy storage-charging station underdeveloped?

The coupled photovoltaic-energy storage-charging station (PV-ES-CS) is an important approach of promoting the transition from fossil energy consumption to low-carbon energy use. However, the integrated charging station is underdeveloped. One of the key reasons for this is that there lacks the evaluation of its economic and environmental benefits.

What are the different types of EV charging–discharging schemes?

Fig. 1 illustrates a general EV charging–discharging scheme with both controlled and uncontrolled charging. Controlled charging is further classified into four sub-groups: indirect controlled, bi-directional controlled, intelligent controlled, and multistage controlled.
