Learn MoreThe 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.
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 capacity planning of charging piles is restricted by many factors. It not only needs to consider the construction investment cost, but also takes into account the charging demand, vehicle flow, charging price and the impact on the safe operation of the power grid (Bai & Feng, 2022; Campaa et al., 2021).
According to the taxi trajectory and the photovoltaic output characteristics in the power grid, Reference Shan et al. (2019) realized the matching of charging load and photovoltaic power output by planning fast charging piles, which promoted the consumption of new energy while satisfying the charging demand of EVs.
The proposed method reduces the peak-to-valley ratio of typical loads by 52.8 % compared to the original algorithm, effectively allocates charging piles to store electric power resources during off-peak periods, reduces user charging costs by 16.83 %–26.3 %, and increases Charging pile revenue.
In the charging and discharging process of the charging piles in the community, due to the inability to precisely control the charging time periods for users and charging piles, this paper divides a day into 48 time slots, with the control system utilizing a minimum charging and discharging control time of 30 min.
