基于MATLAB Simulink的电动汽车与储能系统自适应下垂控制策略优化研究：考虑频率变化与SOC影响,基于自适应下垂控制的电动汽车调频策略优化：结合SOC状态与频率变化的智能调节方法,matlab simulink 电动汽车调频，储能调频，火储调频，自适应下垂，SOC控制。电动汽车相当于储能，可以进行充放电，但是考虑到电动汽车的充电放电应根据频率df变化，储能状态SOC影响，因此对电动汽车控制，根据频率，SOC进行自适应下垂控制优化，传统下垂受到dp=k×df，变化。本文中，电动汽车将传统下垂系数作为k1，将SOC变化作为k2，因此改进下垂系数为k1×k2，这样，在满足调频需求的同时，保障电动汽车的充放电损耗。,matlab;
