Synergetic Development for Power-Transportation Coupling Network in Smart City Environment: A Compressive Review on Analytical Models

The increasing use of electric vehicles (EVs) has created a complex interdependence between the transportation system and the power grid. As a result, analyzing the interplay between these two systems has become crucial. However, most studies have focused on analyzing either the transportation or the power system in isolation, which may not fully capture the complex interactions that occur in the power-transportation coupling network (PTCN). Therefore, this paper explores the existing analytical models of the PTCN, considering network topology, collaborative planning, operation, flow calculation, operating efficiency, and model analysis. The paper identifies the gaps in the current research and provides suggestions for future research, including systems coupling at the operational level, a more specific user equilibrium model, and the security/stability of the PTCN. For instance, further research is needed to better understand the impact of EVs charging and discharging on the power grid, as well as the potential for utilizing EVs batteries to provide grid services. Additionally, a more specific user equilibrium model could help policymakers optimize EVs charging infrastructure and incentives, leading to a more efficient and sustainable transportation system. Finally, ensuring the security and stability of the PTCN is essential for maintaining the reliability of both the transportation and power systems.
