Electric Vehicles Scale Evolution Model Considering Social Attributes

Predicting the scale of electric vehicles at different time is the basis for the power grid to effectively accept charging loads. The development of electric vehicles is not only affected by economy, technology and policy, but also affected by the factors from social networks. This paper proposes the electric vehicle purchase decision model considering the influences of technology, economy and society. A two-dimensional space is used to characterize the random influences of related economic and social groups on consumer decisions, which can dynamically simulate the interaction between social environment and consumer decisions. Thus, based on such two-dimensional social space, an electric vehicle scale evolution model is established, so that it can be used to analyze the impact of the structural characteristics of social networks on the scale evolution. A large community in Changsha is taken as an example to analyze the scale development trend of electric vehicles under different social networks. Case studies demonstrate the feasibility and effectiveness of the proposed methodology.
