考虑由光伏（PV）阵列和质子交换膜燃料电池（PEMFC）组成的混合系统。混合动力系统可采用两种运行模式：单位功率控制（UPC）模式和馈线流量控制（FFC）模式。可再生能源目前得到广泛应用。这些资源之一是太阳能。光伏 (PV) 阵列通常使用最大功率点跟踪 (MPPT) 技术，在辐照和温度发生变化时持续向负载提供最高功率。为了克服这些固有的缺点，应在混合动力系统中安装替代能源，例如 PEMFC。通过改变FC输出功率，混合源输出变得可控。因此，必须确定混合源输出的参考值。所提出的具有灵活的运行模式改变的运行策略始终使光伏阵列以最大输出功率运行，并使质子交换膜燃料电池在其高效率性能范围内运行，从而提高系统运行性能，增强系统稳定性，并减少运行模式改变的次数。使用名为 MATLAB SIMULINK 的仿真软件来仿真系统性能。
The hybrid system composed of a Photovoltaic (PV) array and a Proton exchange membrane fuel cell (PEMFC) is considered. Two operation modes, the unit-power control (UPC) mode and the feeder-flow control (FFC) mode, can be applied to the hybrid system. Renewable energy is currently widely used. One of these resources is solar energy. The photovoltaic (PV) array normally uses a maximum power point tracking (MPPT) technique to continuously deliver the highest power to the load when there are variations in irradiation and temperature. In order to overcome these inherent drawbacks, alternative sources, such as PEMFC, should be installed in the hybrid system. By changing the FC output power, the hybrid source output becomes controllable. Therefore, the reference value of the hybrid source output must be determined. The proposed operating strategy with a flexible operation mode change always operates the PV array at maximum output power and the PEMFC in its high efficiency performance band, thus improving the performance of system operation, enhancing system stability, and decreasing the number of operating mode changes. A simulation software known as MATLAB SIMULINK has been used to simulate the system performance.
