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.
With the continual progress of charging technology, the overall charging power of public charging piles has steadily increased. In the past three years, the average power of public DC charging piles has exceeded 100 kW to meet the requirements of long range and short charging duration of electric 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.
The configuration of public AC charging piles has changed, i.e., from 7 kW AC charging pile to 20 kW/40 kW three-phase AC charging pile. The available charging powers of DC charging piles include 30, 60, 120, 240 and 380 kW (Fig. 5.4). Source China Electric Vehicle Charging Infrastructure Promotion Alliance (EVCIPA)
By the end of 2020, the units in operation (UIO) of public charging piles in China was 807,000, and the number of new charging piles had increased significantly. With the continuous development of the scale market of new energy vehicles, the number of public charging infrastructures in China have grown rapidly.
Considering that the quantity of served EVs in the initial planning period in this paper is about 25 thousand, the CDs can be low in non-charging hotspot areas, thus, the minimum number of charging piles N p, min CS is limited to 2; The maximum number of charging piles N p, max CS is limited to 50 considering the costs and spatial factors.
