摘要
设计和搭建由光伏(PV)、燃料电池(FC)、蓄电池(Battery)和直流负载(Load)等构成的混合直流微电网系统,对系统的供电模式和能量流动方式进行优化设计,以上海地区日照强度和负载功耗为例,借助Matlab/Simulink对系统进行建模。模拟结果与实验结果吻合性较好,新型混合直流微电网系统较好地克服了光伏发电间歇性和燃料电池输出功率不稳定的影响,光伏与燃料电池搭配使整个系统具有较高的稳定性和实用性。
In this paper,a new hybrid DC micro-grid system consisting of PV,fuel cell,battery and load is designed,and the hybrid power supply mode and energy flow mode of the system are optimized.With the sunshine radiation intensity and DC load power consumption in Shanghai as an example,the system is modeled by using the software of MATLAB/Simulink.The simulation results are in good agreement with the experiment.The new hybrid DC micro-grid system can better overcome the adverse effects of intermittent photovoltaic power generation and unstable output power of fuel cells.The combination of photovoltaic and fuel cell makes the whole system more stable and practical.
