摘要

考虑双有源桥（DAB）流变换器在储能应用场景,建立双端口DAB等效数学模型;在不同移相条件下推导回流功率、传递功率与移相角之间的函数关系。根据适应度函数和惩罚函数,提出双重移相与鲸鱼算法结合的控制策略（DPS-WOA）,可抑制回流功率;该策略可获得全移相比范围内恒定传输功率情况下的最小回流功率移向比组合。DPS-WOA工作原理是：通过鲸鱼优化算法（WOA）对双重移相（DPS）控制方法下的DAB回流功率模型进行最小值求解。对比现有的单重移相（SPS）、DPS、三重移相（TPS）传统优化控制方案验证了控制策略具有更好的回流功率优化能力和全移向范围优化能力。

Abstract

The return power control of dual active bridge （Dual Active Bridge, DAB） DC converters has attracted much attention. Suppressing the return power can improve the conversion efficiency of DAB. Considering the application scenarios of DAB DC converters in energy storage, a two-port DAB equivalent mathematical model is established. The function relationship between the return power, the transmitted power and the phase shift angle is derived under different phase shift conditions. According to the fitness function and the penalty function, a dual-phase-shift control with Whale Optimization Algorithm （WOA） is proposed to suppress the return power. This strategy can achieve the full-shift comparison range The minimum return power shift ratio combination in the case of constant transmission power. The working principle of DPS-WOA is to solve the minimum value of the DAB return power model under the DPS（Dual-Phase-Shift） control method through the Whale Optimization Algorithm （WOA）. Compared with the existing SPS （Single-Phase-Shift）, DPS, and TPS （Triple-Phase-Shift） traditional optimization control schemes, it is verified better return power optimization capability and full shift range optimization capability of the control strategy.
