The behavior of this type of car is generally flexible and has a high probability of leaving early. The charging pile charges the battery with the maximum charging power and each vehicle pays the charging price. (1) P n, c, t s = P n max (2) u n, c, t s = u t b + α
As the number of electric vehicles (EVs) increases, EV charging demand is also growing rapidly. In the smart grid environment, there is an urgent need for green charging stations (GCS) to effectively manage the internal photovoltaic (PV), energy storage system (ESS), charging behaviors of EVs and energy transactions with entities.
Energy piles are a type of green foundations that can reduce the amount of energy consumed for space heating and cooling by up to 75%. It is inevitable that the operation of energy piles imposes heating and cooling cycles not only the pile but also the surrounding soil.
In this paper, we consider a green charging station shown in Fig. 1. In addition to charging piles, GCS also integrate PV and ESS. The charging station is connected to the main grid through the local distribution network, and the two-way interaction can be realized through the physical and communicational network.
On the other hand, a cooled pile also had an apparent increase in pile capacity as compared with that of a non-cooled pile. This was attributed to pile settlement during cooling, leading to an increase in toe resistance due to compaction of soil below the pile toe.
Basic data In the case study, a green charging station equipped with PV and ESS is considered. The total time of scheduling, i.e., a day, is entirely divided into T = 24 time points and each time interval is an hour. We assumed that there are the same number of three types of EVs in the CS, ten EVs for each type, in the CS.
