本文提出了一种由光伏（PV）阵列和聚合物电解质膜燃料电池（PEMFC）组成的混合能源系统的能量管理方法。两种存储设备（锂离子电池模块和超级电容器（SC）组）在拟议的结构中用作高能量高功率密度存储设备。多段转换器的PV，燃料电池（FC），电池，和SC提出了电网独立应用。研究了基于非线性差分平坦度的模糊控制在电厂直流母线稳压中的应用。为了验证控制方法，硬件系统实现了PV， FC，电池和SC电流控制回路（内部控制器回路）的模拟电路，以及外部能量控制回路的数值计算（dSPACE）。小型设备的实验结果[光伏阵列（800W, 31 a）， PEMFC组（100 F, 32 V）]证明了负载周期内出色的能量管理方案。
This study presents an energy management approach for a hybrid energy system comprised of a photovoltaic (PV) array and a polymer electrolyte membrane fuel cell (PEMFC). Two storage devices [a Li-ion battery module and a supercapacitor (SC) bank] are used in the proposed structure as a high-energy high-power density storage device. Multisegment converters for the PV, fuel cell (FC), battery, and SC are proposed for grid-independent applications. Nonlinear differential flatness-based fuzzy logic control for dc-bus voltage stabilization for power plant is investigated. To validate the control approach, a hardware system is realized with analog circuits for the PV, FC, battery, and SC current control loops (inner controller loops), and with numerical calculation (dSPACE) for the external energy control loop. Experimental results with small-scale devices [a PV array (800W, 31 A), a PEMFC bank (100 F, 32 V)] demonstrate the excellent energy-management scheme during load cycles.
