摘　　要：以矿区风光储一体化微网的双有源桥直流变换器功率环流为研究对象,针对当其输入、输出电压不匹配时会产生较大回流功率的问题,提出了一种回流功率全局优化的三重移相控制策略。首先,建立了能够描述变换器工作特性的数学模型,并推导了传输功率和回流功率的方程;然后,通过应用全局优化函数,在宽传输功率范围内选出移相角最优组合,使其回流功率最小;最后,根据优化控制策略搭建了实验样机,将所提出的优化控制策略与传统的三重移相控制策略在不同传输功率下的回流功率进行了比较。实验结果表明,所提优化控制策略在减少回流功率方面表现出色,显著提升了变换器的性能,充分证实了所提控制策略是正确的和有效的。The power circulating current of the dual active bridge DC converter in the integrated microgrid of wind,solar and energy storage in mining areas was taken as the research object.A triple phase shift control strategy for global optimization of reflux power was proposed to address the problem of large reflux power generated when the input and output voltages were not match.Firstly,the mathematical model that able to describe the performance characteristics of the converter was constructed,and the equations of the transmitted power and the reflux power were derived.Then,the optimal phase shift angle combination was selected within a wide transmission power range to minimize its reflux power,by applying global optimization functions.Finally,an experimental prototype was built according to the optimized control strategy,and the reflux power of the proposed optimized control strategy was contrast with the traditional triple phase shift control strategy at different transmission powers.The experimental results show that the proposed optimized control strategy performed well in reducing the reflux power and promoted the function of the converter significantly,which fully confirmed that the proposed control strategy was correct and effective.
