Abstract

The present invention discloses a fuel cell system domain controller (FDCU) and a control method, relating to the field of fuel cell system control. The control method comprises the following steps: S1, performing multi-dimensional grouping of power supply channels to decompose complex multi-port power flows into simplified multi-port / two-port converter topologies; S2, real-time monitoring of the operating status of BOP components and predicting the changing trend of component power requirements; S3, selecting the optimal grouping scheme based on the changes in BOP component power requirements, adjusting the grouping of power supply channels in real time, and adjusting the converter topology connection mode; S4, controlling each power supply channel through PID control, adjusting the output voltage / current in real time, and dynamically adjusting the grouping strategy weight according to the system urgency. The present invention achieves a comprehensive improvement in fuel cell system power supply efficiency, control stability, flexibility, and cost through converter topology optimization techniques that include multi-dimensional grouping, dynamic adjustment of power supply strategies, and reconstruction of power flow paths.
