Abstract This work presents a dynamic simulation model of a prototypal renewable plant producing electricity, heat and cool. The hybrid system consists of a 6 kWe Organic Rankine Cycle (ORC), a 17.1 kWf absorption chiller, a geothermal well, a 25 m2 evacuated solar collector field, a 200 kWt biomass heater and a 45.56 kWh electric energy lithium-ion storage system. The geothermal well at 96 °C, in combination with the solar field, supplies the thermal energy driving the ORC. This simulation model is implemented in TRNSYS environment. In order to evaluate the thermoeconomic performance of this renewable trigeneration plant, a suitable case study is analysed: a bar and soccer centre in the area of Campi Flegrei (Naples). By the simulation, interesting results in terms of energy and environmental performance are obtained. The proposed renewable power plant achieves a primary energy saving of 94.54% and a reduction of CO2 emissions equal to 97.36%. The high total capital cost of the plant significantly affects the payback period of 16.7 years. However, in the future European energy scenarios, where a full decarbonization will be achieved and the capital cost of the renewables will significantly decrease, the use of these technologies will be pivotal and significantly profitable.

小型混合太阳能地热三联产系统的能源和经济分析：一种动态方法

摘要 这项工作提出了一种可发电、供热和制冷的原型可再生植物的动态仿真模型。该混合系统由一个 6 千瓦的有机朗肯循环 (ORC)、一个 17.1 千瓦的吸收式制冷机、一个地热井、一个 25 平方米的真空太阳能集热器场、一个 200 千瓦的生物质加热器和一个 45.56 千瓦时的电能锂离子存储系统组成。96 °C 的地热井与太阳能场相结合，提供驱动 ORC 的热能。该仿真模型在 TRNSYS 环境中实现。为了评估该可再生三联产电厂的热经济性能，我们分析了一个合适的案例研究：Campi Flegrei（那不勒斯）地区的一个酒吧和足球中心。通过模拟，在能源和环境性能方面获得了有趣的结果。拟建的可再生发电厂实现一次节能 94.54%，二氧化碳排放减少 97.36%。工厂的高总资本成本显着影响了 16.7 年的投资回收期。然而，在未来的欧洲能源情景中，将实现完全脱碳，可再生能源的资本成本将显着降低，这些技术的使用将是关键和可观的利润。
