Stochastic Simulation of Electric Vehicle Charging Behavior and Charging-Simultaneity-Factor Calculation Method Based on Gaussian Mixture Model
To address the expansion planning of electric vehicle(EV) charging stations and improve the utilization of charging piles
a method for calculating the simultaneity factor is proposed. A Gaussian mixture model(GMM) and a Monte Carlo algorithm-based queuing model is used to simulate user charging behavior
thereby calculating the optimal vehicle-to-pile ratio and simultaneity factor. The influence of multi-scenario factors on the simultaneity factor is investigated
and a charging facility design framework for different scenarios in residential and commercial areas is established. By analyzing charging power characteristic curves of private vehicles
the charging simultaneity factor for diverse scenarios is measured. Case study results demonstrate the effectiveness and feasibility of the proposed method
providing valuable insights for the planning and construction of EV charging stations.
