摘要
为实现以可再生能源为全部能源来源的绿色建筑设计,笔者提出将氢储能应用于民宿建筑独立微电网系统,并研究微网系统容量配置。首先,构建以总净现值成本最低为优化目标、以负荷缺电率等为约束的含氢储能独立微网系统模型;然后,采用HOMER Pro软件优化配置系统容量,并对比分析7种组合方案的配置结果和系统运行状态;最后,对最优配置方案的氢储能系统价格进行灵敏度分析。结果表明:风力发电机在系统中发挥的作用较小,不适合安装;由此确定最优容量配置方案为光伏发电13.1 kW、蓄电池4 kW·h、电解槽8 kW、燃料电池5 kW、储氢罐2 kg。该方案可实现100%可再生能源发电,经济成本最低,负荷缺电率约为0。
In order to realize the green building design with renewable energy as the whole energy source the authors propose to apply hydrogen energy storage to the independent microgrid system of homestay building and study the capacity configuration of microgrid system.Firstly an independent microgrid system model with hydrogen energy storage is constructed with the minimum total net present value cost as the optimization objective and the load power shortage rate as the constraint Then HOMER Pro software is used to optimize the system capacity and the configuration results and system operation status of the seven combination schemes are compared and analyzed Finally sensitivity analysis is conducted on the price of the hydrogen energy storage system with the optimal configuration scheme.The results show that wind turbines play a relatively small role in the system and are not suitable for installation The optimal capacity configuration scheme is determined to be 13.1 kW for photovoltaic power generation 4 kW∙h for batteries 8 kW for electrolytic cells 5 kW for fuel cells and 2 kg for hydrogen storage tanks.The scheme can achieve 100%renewable energy power generation with the lowest economic cost and the load power shortage rate of about 0.
