Trip Chain Simulation of Electric Vehicles based on NHTS Data

It has great potential that electric vehicles (EVs) participate in the regulation and control of the power grid. However, due to randomness of EV in use, it is necessary to determine their spatial and temporal distribution status. Based on the latest released National Household Travel Survey (NHTS) data, this paper fits the temporal and spatial feature information of the EV trip chain and makes corresponding improvements to the deficiencies in the existing research. The stochastic simulation method is used to simulate the trip chain, and the simulation results are verified and analyzed, which shows that the method can accurately simulate the EV trip chain and can provide strong support for the subsequent EV participation in the analysis of grid control operations.
