Increasing the revenue from hotel operations and decreasing the stress on utility grids from hotel energy consumption are two priorities for the modern tourism industry. Dynamic occupancy rate and hotel reservation prices influence their operations revenue, while occupancy rate also impacts real hotel energy consumption. Renewable power generation as an effective measure can benefit hotels not only by decreasing electricity purchases but also increasing some extra income from selling electricity generated from renewable sources. This study investigated the effects of renewable power generation on energy and the cost-benefit performance of hotel operation prices under different occupancy rates and reservation prices. A two-stage energy and cost-benefit performance assessment and a novel comprehensive cost-benefit assessment model were developed to examine these research issues. The impact of the renewable power generation system (i.e., a photovoltaic-battery system installed on the building rooftop) was considered on the hotel energy and cost-benefit performance. It was found that the novel cost-benefit assessment model accurately quantified the overall hotel profit by calculating its energy consumption cost with the PV-battery system under different occupancy rates and reservation prices. Three typical homestay hotels located in Sanya were tested and assessed. The results showed that PV-battery systems effectively decreased the amount of electricity purchased by hotels. Besides, the renewable energy penetration was above 57.98% in various cases. The overall hotel profit increased by a maximum of 31.4% since renewable power generation was used under different occupancy rates and hotel reservation prices.

寄宿酒店应用可再生能源发电的评估：考虑动态入住率和预订价格的能源和成本效益

增加酒店运营收入和减轻酒店能源消耗对公用电网的压力是现代旅游业的两个优先事项。动态入住率和酒店预订价格影响其运营收入，而入住率也影响酒店的实际能源消耗。可再生能源发电作为一种有效的措施，不仅可以减少酒店的购电量，还可以通过出售可再生能源产生的电力来增加一些额外收入，从而使酒店受益。本研究调查了可再生能源发电对能源的影响以及不同入住率和预订价格下酒店运营价格的成本效益表现。开发了两阶段能源和成本效益绩效评估以及新颖的综合成本效益评估模型来研究这些研究问题。考虑了可再生能源发电系统（即安装在建筑屋顶的光伏电池系统）对酒店能源和成本效益的影响。结果发现，新颖的成本效益评估模型通过计算不同入住率和预订价格下光伏电池系统的能源消耗成本，准确量化了酒店的整体利润。对位于三亚的三家典型民宿酒店进行了测试和评估。结果表明，光伏电池系统有效减少了酒店的购电量。此外，可再生能源渗透率多次达到57.98%以上。由于在不同入住率和酒店预订价格下使用可再生能源发电，酒店整体利润最高增长31.4%。
