Results show that during the planning period, the installation number of energy storage charging piles will significantly increase when V2G proportions expands. The total costs consistently show a descending trend if EVs participating more in V2G. When the V2G proportions increase from 25 % to 100 %, the total CO 2 emissions decrease by 4.49 %.
Scholars have found that the construction of charging pile facilities plays a positive role in the development of new-energy vehicles. Policies supporting EV construction cultivate the EV market, with technical advances and subsidies in China promoting future progress of the EV industry .
The charging pile industry is in full development with the expansion of the investment blueprint of new infrastructure in China. As new-energy vehicles are being promoted in China, the construction of charging piles, as important infrastructure, has gradually attracted attention.
The development of the new-energy vehicle charging pile network began reasonably early, around 2016, in each of these three provinces. However, none of the provinces has advantages in the industrial chain, and the automobile industry is weak in these provinces.
The study then transforms time-series data of the EV charging piles into a complex network by applying a visibility graph, uses several clustering methods to categorize different provinces, and predicts the future development of the network of EV charging piles in China.
Construction of the time-series network and extraction of features. The new monthly increase in the number of charging piles of new-energy vehicles had small peaks in September 2016, December 2018, February 2018, January 2019, and March 2019. Table 1 shows that important relevant policies were launched before and after some of these peaks.
Additionally, the strengths and clustering coefficients of the three networks are similar, with medium values having the highest frequency, which indicates that the development of the network of EV charging piles is steady and provinces in China are well connected and coordinated in the advance of EV infrastructure.
Results show that during the planning period, the installation number of energy storage charging piles will significantly increase when V2G proportions expands. The total costs consistently show a descending trend if EVs participating more in V2G. When the V2G proportions increase from 25 % to 100 %, the total CO 2 emissions decrease by 4.49 %.
