A hybrid simulation method for EVs' operation considering power grid and traffic information

Abstract

As the penetration of electric vehicles (EVs) increases, it is required to consider both power grid and traffic information when analyzing EVs distribution and charging loads. This paper presents a hybrid simulation method for real-time operation of EVs, charging stations, traffic and the grid. It first describes the traffic model and electric model and builds a hybrid model for EVs to combine these two models. The paper presents a detailed timing simulation method afterwards. After generating EV inflows and traffic flows in different places and setting EV's charging behavior, EVs' State of Charge (SOC) and spatial moving and charging stations' working states can be viewed through simulation. An example is presented to illustrate the impact of EV inflows on the charging power of charging stations. This method can be applied in other researches, and it will be utilized for future research work on the interaction between power grid and traffic network.
