Power Adaptive Allocation Strategy for Multi-stack Fuel Cell Performance

In order to improve the output power of multi-stack fuel cell (MFC) system and delay the decline of single-stack life, this paper proposes an adaptive power distribution method for MFC power generation system based on the operational performance of the power stacks, each power stack is connected to a DC/DC converter separately to realize the system power regulation, and the virtual sag control algorithm is used to realize the adaptive power distribution. It can realize the adaptive power distribution, and the method can make the DC bus voltage maintain stable and help enhance the stability of the system and improve the output power.
