Abstract
The work discusses intermittent light scheduling for energy cost reduction in vertical farming, specifically for growing salad crops (Lactuca Sativa). The study explores how dynamically adjusting lighting schedules based on day-ahead energy prices can improve energy efficiency and reduce operational costs. The research uses a growth chamber equipped with LED lights, controlled environmental factors, and real-time data from the Nord Pool energy market to optimize energy use. The results show that intermittent lighting schedules, aligned with cheaper energy periods, lead to higher crop yields and significant energy cost savings compared to continuous lighting. The findings suggest that such adaptive lighting strategies can make vertical farming more economically viable and sustainable by optimizing resource use, aligning with global sustainability goals. The study also highlights the potential of vertical farms to act as flexible power consumers, adjusting their energy usage based on renewable energy availability.
该研究讨论了在垂直耕作中,特别是在种植沙拉作物(Lactuca Sativa)时,如何通过间歇性光照调度来降低能源成本。该研究探讨了根据日前能源价格动态调整照明计划如何提高能源效率和降低运营成本。研究利用配备 LED 灯的生长室、可控的环境因素和来自 Nord Pool 能源市场的实时数据来优化能源使用。结果表明,与连续照明相比,与能源价格较低的时段相一致的间歇性照明计划可提高作物产量,并显著节约能源成本。研究结果表明,这种自适应照明策略可以通过优化资源利用,使垂直农业更具经济可行性和可持续性,从而与全球可持续发展目标保持一致。研究还强调了垂直农场作为灵活用电者的潜力,可根据可再生能源的可用性调整能源使用。
