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 …
With the gradual popularization of electric vehicles, users have a higher demand for fast charging. Taking Tongzhou District of Beijing and several cities in Jiangsu Province as examples, the charging demand of electric vehicles is studied. Based on this, combining energy storage technology with charging piles, the method of increasing the power …
Due to the endurance characteristics of EVs, the travel route is often changed due to the charging demand of EVs. As shown in Fig. 1, during a journey from a departure place to the destination, once an EV has a charging demand, it needs to be recharged such that it can reach the destination. ...
