What is a rechargeable energy storage system?

"Rechargeable energy storage system (REESS)" means the rechargeable energy storage system that provides electric energy for electrical propulsion. The REESS may include subsystem(s) together with the necessary ancillary systems for physical support, thermal management, electronic control and enclosures.“ 2.34.

How does discharge time affect EV charging capacity?

However, with the increase of discharge time, the discharging pressure of EV users decreases gradually, so the discharge capacity of electric vehicle reduces significantly at 10 h–13 h. The charging capacity of EVs decreases significantly at 15 h and 17 h.

Does a larger charge discharge pressure increase the cost of EV users?

As designed by the cost function (33), a larger charge discharge pressure of EV will increase the cost of EV users. 3.4.2. IMG operator The IMG operator aims to operate the domestic network at a minimum operating cost while integrating the flexibility potentials of the PEVs into the main grid.

Does low electricity price affect the discharge capacity of EVs?

When considering the charging and discharging pressure of EV users, the discharging pressure decreases due to the low electricity price at 7 h–8 h, resulting in the reduction of the discharge capacity of EVs. It can be observed from Fig. 8 (b) that the discharge capacity of EVs increases at 18 h–19 h.

Why do EVs have a low charge capacity?

It not only reduces the power cost of electric vehicles, but also maintains the stability of the main power grid. Since EVs mainly arrive at 7 h and the average SoC is 0.6, there is less charge capacity in the low price range.

Why does EV charging capacity decrease at 15 h and 17 h?

The charging capacity of EVs decreases significantly at 15 h and 17 h. One reason is that the SOC increases due to the reduction of early discharge capacity, resulting in the decrease of charging pressure of EVs. Another reason is that positive EV users account for the majority and are not in a hurry to charge.
