提出了一种新的控制策略，用于以聚合物电解质膜燃料电池为主要能源、超级电容器为辅助电源的分布式发电系统中的调压直流混合电源。该策略是基于一个标准的直流环节电压调节，这是简单的比标准的状态机用于混合源控制，和自由的抖动问题。其独创性在于仅使用存储设备来提供实现直流链路电压调节所需的能量。因此，混合动力系统的主电源被认为是一个标准的负载，只工作在再生制动，以保持存储设备充电。文中介绍了系统的总体结构、混合源的控制原理、实验台的实现以及实验验证。
This paper proposes an innovative control strategy for a voltage-regulated dc hybrid power source employing polymer electrolyte membrane fuel cell as the main energy source and supercapacitors as the auxiliary power source for a distributed generation system. This strategy is based on a standard dc link voltage regulation, which is simpler than standard state machines used for hybrid source control, and free of chattering problems. Its originality lies in using only the storage device for supplying the energy required to achieve the dc link voltage regulation. Therefore, the main source of the hybrid system is considered as a standard load, working only in regenerative braking, to keep the storage device charged. The general structure of the studied system, the control principle of the hybrid source, the realization of the experimental bench, and the experimental validation are all presented.
