Abstract

Designing an efficient renewable energy system is critical for achieving cost-effective energy solutions and minimizing excess generation. This study analyzes the optimization of renewable energy systems with two storage configurations: PV solar with Li-ion Batteries (PV-LIB) and PV solar with a reversible fuel cell (PV-RFC). The system maximizes renewable energy integration by optimizing component sizes to meet the buildings load demand. Results indicate that the PV-LIB system requires a smaller PV array than the PV-RFC system due to the higher roundtrip efficiency of Li-ion batteries. The PV-RFC system achieved a renewable fraction of 95.43 %, while the PV-LIB system reached 95.73 %, with 0.068 % excess energy in the PV-RFC system and none in the PV-LIB system. Monthly energy supply distribution analysis highlights the variability of PV generation and the consistent contribution of storage systems. Cost analysis reveals a levelized cost of hydrogen (LCOH) of $5.17/kg and a levelized cost of energy (LCOE) of $0.166/kWh for the PV-RFC system, compared to an LCOE of $0.071/kWh for the PV-LIB system. The PV-LIB system is more economically viable due to lower capital costs and higher efficiency. Both systems demonstrated lower LCOE compared to local grid electricity tariffs, emphasizing their economic advantage.

向更清洁的城市能源迈进：整合光伏、可逆燃料电池和电池

设计一个高效的可再生能源系统对于实现具有成本效益的能源解决方案和最大限度地减少过剩发电至关重要。本研究分析了锂离子电池光伏太阳能（PV- lib）和可逆燃料电池光伏太阳能（PV- rfc）两种储能配置下的可再生能源系统优化。该系统通过优化组件尺寸来最大限度地提高可再生能源的整合，以满足建筑物的负荷需求。结果表明，由于锂离子电池的往返效率更高，PV- lib系统比PV- rfc系统需要更小的PV阵列。PV-RFC系统的可再生能源比例达到95.43%，PV-LIB系统达到95.73%，其中PV-RFC系统有0.068%的多余能源，PV-LIB系统没有多余能源。月度能源供应分布分析强调了光伏发电的可变性和存储系统的一致贡献。成本分析显示，PV-RFC系统的平准化氢成本（LCOH）为5.17美元/千克，平准化能源成本（LCOE）为0.166美元/千瓦时，而PV-LIB系统的LCOE为0.071美元/千瓦时。由于更低的资本成本和更高的效率，PV-LIB系统在经济上更可行。与当地电网电价相比，这两个系统都显示出较低的LCOE，强调了它们的经济优势。
