计及多堆燃料电池功率分配的电氢耦合系统分层控制策略
Hierarchical Control Strategy for Electric-Hydrogen Coupled System Considering the Power Distribution of Multi-Stack Fuel Cells
摘要
Abstract
To address the issues of limited output power in single fuel cells and the low efficiency of electric-hydrogen coupling systems in maintaining stable operation under complex conditions,this paper investigates the power allocation strategy for multi-stack fuel cell systems(MFCS)and proposes an electric-hydrogen coupling layered energy management strategy that considers the power allocation of multi-stack fuel cells.A layered energy management strategy is introduced,dividing the control system into a state-machine control layer and a device control layer.The multi-stack fuel cell power allocation method is designed to optimize fuel cell efficiency.The upper layer,the state-machine control layer,collects data on residual system power,the state of charge(SOC)of the lithium battery,and the state of hydrogen(SOH)in the hydrogen storage tank.The lower layer,the equipment control layer,receives switching signals from the state machine to control each device,selecting different control modes.This allows the fuel cells to operate within their normal range as much as possible,improving their life and efficiency,reducing system state switching,enhancing the system's anti-disturbance capabilities,and efficiently utilizing photovoltaics.Simulations based on the Simulink platform verified the effectiveness of the proposed hierarchical control strategy.关键词
