[@Tushar]. Although they are not massively deployed, these examples demonstrate the technique feasibility for charging EVs/PEVs by renewable energy.

Prior works [@Rahbari-Asr]-[@Ghavami] have considered regulations of EV loads in a distribution network. Rahbari-Asr *et al.* in [@Rahbari-Asr] consider to maximize the total utility of PEV/EV users, as well as avoiding line/node overload. The distributed charging regulation algorithms are designed to ensure certain system optimality and line constraints by means of utility maximization framework and game theory in [@Ardakanian] and [@Ghavami], respectively. The scheme in [@Ardakanian] also considers the effects of residential loads on overloading the same distribution network that provides charging service to EVs. The similar effects are further discussed in [@Safdarian]-[@MaHu]. In general the above works regard EVs as time shiftable loads and regulate them to charge at different time slots in order to maintain power network safety and decrease electricity cost by utilizing the time diversity of electricity price. In other words, [@Ardakanian]-[@Angelis] and [@Sun1] are more suitable for slow charging scenario. As for fast charging, it usually lasts for less than one hour with large power consumption. Thus where to charge turns to be another practical problem, since it is important to avoid overload at individual place
