摘要
V2G作为一种新的分布式储能模式,能够有效参与电网的负荷平抑、峰谷调节,位置灵活且易于产生巨大的经济效益。双有源桥变换器是V2G中重要的组成部分,具有良好的电气隔离、电能变换能力。然而,在V2G这种功率双向、输出电压范围宽、恒功范围宽的工作场合,双有源桥变换器的设计成为了一大难题。提出一种基于最优效率的双有源桥变换器参数设计优化方法,能够综合频率、器件、功率、磁性器件、控制方法、输出电压范围、输入输出电压匹配关系等优化参数,设计出最优效率的双有源桥变换器。
As a new way of distributed storage system,V2G can effectively realize load stabilization and regulation of power grid,and is easy to produce huge economic benefits.Dual active bridge converter is an important part for V2G,which has good electrical isolation and power conversion ability.However,V2G needs bidirectional power ability,wide output voltage range and wide power range,which complex the design of dual active bridge converter.In this paper,a design method of dual active bridge based on the optimum efficiency is proposed,which can consider all the parameters,such as frequency,device,power,magnetic component,control method,output voltage range and input-output voltage relationship,and obtain the dual active bridge converter with optimal efficiency.
