家庭负载频繁出现瞬间的峰值功率需求,由燃料电池/蓄电池组成的混合发电系统是最清洁和高效的发电方式之一。燃料电池仅满足基本负载,由蓄电池放电以满足瞬间的峰值功率需求。研究了一个60kW家用混合发电系统,该系统由质子交换膜燃料电池(PEMFC)和阀控铅酸蓄电池组成,设计为10个家庭同时供电。在保证系统可靠性和持久性的同时,为了提高整个混合发电系统的工作效率和燃料经济性,在系统仿真和分析的基础上详细描述了一种基于规则的能量优化控制策略。仿真实验结果表明,与燃料电池单独供电相比,60kW混合发电系统通过优化2种能源之间的功率分配,能够在响应负载的同时提高整个发电系统的工作效率和燃料经济性。
With frequent peak load demands on household loads, a hybrid power system consisting of fuel cells / batteries is one of the cleanest and most efficient ways to generate electricity. Fuel cells only fulfill the basic load, discharged by the battery to meet the instantaneous peak power requirements. Studied a 60kW home hybrid power system that consists of a proton exchange membrane fuel cell (PEMFC) and a valve-regulated lead-acid battery designed to supply electricity to 10 homes at the same time. To ensure system reliability and durability, a rule-based energy optimization control strategy based on system simulation and analysis is presented in order to improve the working efficiency and fuel economy of the hybrid power generation system. The simulation results show that the 60kW hybrid power system can improve the efficiency and fuel economy of the entire power generation system in response to the load by optimizing the power distribution between the two energy sources, compared with the single power supply of the fuel cell.
