基于微观交通流模型的城市快充负荷精细化实时仿真框架
Real-time Simulation Framework of Urban EVs Charging Loads Based on Micro-level Modeling of Transportation Network
摘要
Abstract
Electric vehicles are rapidly gaining popularity,and various fast and ultra-fast charging stations are continuously increasing in power.This leads to the prominent real-time fluctuation characteristics of urban charging loads.This study proposes a real-time simulation framework for urban fast-charging loads based on micro-level modeling of the transportation network.First,considering micro-level traffic behaviors such as vehicle following,overtaking,and lane-changing,a detailed traffic network model is established to illustrate the impact of the operational status of the traffic network and charging facilities on driving behavior and charging choices.Then,a traffic travel matrix is established to allocate electric vehicle travel demands.Factors such as time,distance,and prices are considered for individual electric vehicle charging choices.Finally,through a second-by-second simulation of electric vehicles' driving and charging decision-making processes in the micro-level traffic network,the real-time dynamic changes in traffic flow and fast-charging station charging loads are obtained.Using simulation examples based on the actual traffic network in Nanjing,the dynamic characteristics of charging loads are fully demonstrated,providing a powerful analytical foundation and simulation tool for fine-grained charging load scheduling.关键词
