基于充放电自由度的小型电动乘用车集群响应能力评估模型OA

To investigate the characteristics of the responsive capacity(RC)variations of small-scale electric pas-senger vehicle clusters participating in power grid regulation,a responsive capacity evaluation model based on char-ging and discharging flexibility is proposed.This model aims to address the issues of insufficient response capacity and uneven state of charge(SOC)distribution within electric vehicle(EV)clusters under demand response sce-narios.Based on the responsive capacity model constrained by EV SOC and power limitations,an EV responsive capacity calculation model incorporating charging and discharging flexibility is established.By integrating travel chain rules,the travel patterns of three different types of EV user groups are simulated.The proposed concept of charging and discharging flexibility evaluates the influence of short-term and long-term responsiveness of small-scale electric passenger vehicles.Simulation results indicate that EVs can flexibly adjust their operations under demand variations.The proposed regulation strategy effectively mitigates locally high or low SOC levels,ensuring a more balanced SOC distribution within the regulated EV clusters.The study verifies the effectiveness of the charging and discharging flexibility-based responsive capacity evaluation model and regulation strategy for small-scale electric passenger vehicle clusters.
