Abstract

Abstract The current research investigated the utilization of fuel cells as an energy storage unit in microgrid energy system applications in an effort to enhance self-consumption of renewable energy. The prototype evaluation is constructed of solar photovoltaic and fuel cell energy storage units. The study utilizes experimental weather and electrical load data for household obtained at 1-min temporal resolution. The daily average energy consumption for the evaluated household was 10.3 kWh, with a peak power output of 5.4 kW and an annual energy consumption of 3757 kWh. The Solar System under investigation has a capacity of 3.6 kWp, while the fuel cell system has a capacity of 0–3 kW, allowing for effective integration with the photovoltaic system and a maximum renewable energy fraction. The research indicates that by installing fuel cells powered by hydrogen generated from renewable energy sources, self-consumption and self-sufficiency significantly increase. The annual energy flow demonstrated that the implementation of 2.5 kW fuel cells improved renewable fraction utilization from 0.622 to 0.918, while increasing energy self-consumption by 98.4% to 3338.2 kWh/year and self-sufficiency by 94.41% to 3218.8 kWh/year.

以最高可持续性优化混合动力系统

摘要:本课题旨在探讨燃料电池作为储能单元在微电网能源系统中的应用，以提高可再生能源的自消纳能力。构建了太阳能光伏和燃料电池储能单元的原型评估。该研究利用了以1分钟时间分辨率获得的实验天气和家庭用电负荷数据。被评估家庭的日均能耗为10.3千瓦时，峰值输出功率为5.4千瓦时，年能耗为3757千瓦时。被调查的太阳能系统的容量为3.6 kWp，而燃料电池系统的容量为0-3 kW，允许与光伏系统有效集成，并最大限度地利用可再生能源。研究表明，通过安装以可再生能源产生的氢为动力的燃料电池，自我消耗和自给自足将大大增加。年度能量流表明，2.5 kW燃料电池的实施将可再生能源利用率从0.622提高到0.918，同时将能源自用提高98.4%至3338.2 kWh/年，将自用提高94.41%至3218.8 kWh/年。
