At the same time, although the energy loss in the round-trip conversion is considerable, the hydrogen storage solution is suitable for long charging/discharging periods due to the high energy density per unit of mass and long-term stability in its stored form .
The energy storage charging pile achieved energy storage benefits through charging during off-peak periods and discharging during peak periods, with benefits ranging from 699.94 to 2284.23 yuan (see Table 6), which verifies the effectiveness of the method described in this paper.
Figure 4 shows that the solar-hydrogen-storage-integrated electric vehicle charging station (SHS-EVCS) is a type of electric vehicle charging station that uses solar energy, hydrogen energy storage, and battery energy storage as the main power sources.
On the other hand, even though the hydrogen storage system can be considered a single energy storage solution, it has been divided into two conversion systems (e.g., electrolyser and fuel cell) plus one storage (e.g., hydrogen tank) to evaluate the power and energy decoupling nature of this solution.
Charging piles are of great significance to developing new energy vehicles, and they are also an important part of the emerging digital economy such as intelligent traffic and intelligent energy. The State Grid Corporation of China (SGCC) is taking an active role in the development of new energy vehicles.
Based Eq. , to reduce the charging cost for users and charging piles, an effective charging and discharging load scheduling strategy is implemented by setting the charging and discharging power range for energy storage charging piles during different time periods based on peak and off-peak electricity prices in a certain region.
