Deployment of public charging infrastructure in anticipation of growth in EV sales is critical for widespread EV adoption. In Norway, for example, there were around 1.3 battery electric LDVs per public charging point in 2011, which supported further adoption. At the end of 2022, with over 17% of LDVs being BEVs, there.

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.
Based on the flat power load curve in residential areas, the storage charging and discharging plan of energy storage charging piles is solved through the Harris hawk optimization algorithm based on multi-strategy improvement.
Energy storage and PV system are optimally sized for extreme fast charging station. Robust optimization is used to account for input data uncertainties. Results show a reduction of 73% in demand charges coupled with grid power imports. Annual savings of 23% and AROI of ∼70% are expected for 20 years planning period.
The number of charging piles is decided based on the number of electric bus charging at the same time. ESS capacity and maximum exchange power are decided according to the maximum amount of ESS energy and exchange power in a day. These three parts compose the planning scheme of the electric bus system.
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.
