The warm-up process is a critical operation phase for mCHP plants, directly impacting their efficiency, reliability, and lifetime. As small decentralized power generation units are increasingly expected to be operated on demand, start-ups will occur more frequently and thus the importance of the warm-up process will further increase. In this study, we address this problem by presenting a mathematical optimization framework that finds optimal actuator trajectories that significantly reduce the warm-up time and improve the thermal efficiency of an mCHP plant. The proposed optimization framework is highly flexible and adaptable to various objective functions, such as maximizing efficiency or minimizing the deviation from desired temperature references. The underlying mathematical model has been experimentally validated on a physical mCHP test rig. Selected case studies further demonstrate the effectiveness and flexibility of the framework and show that with the optimized actuator trajectories, the mCHP plant can reach its steady-state operating temperature in 40% less time. The results also indicate that the shortest warm-up time does not necessarily lead to the highest thermal efficiency. Accordingly, the methodology proposed in this paper provides a powerful tool to study higher-level operational strategies of mCHP plants and thus to maximize their overall performance, which directly translates into an improved operational cost-effectiveness, particularly in demand-driven energy landscapes.

“…Além dos trabalhos mencionados, estudos mais recentes mostram que ciclos combinados híbridos continuam contribuindo para solucionar problemas técnicos e aumentar a eficiência de usinas termelétricas. Suas variações têm sido exploradas com foco no aproveitamento de fontes renováveis, como a integração de energia solar com geotérmica [33], [34], biomassa [35], [36] e RSU [37], considerando análises energéticas [38], exergéticas [39], econômicas [31] e ambientais [40], ou ainda em configurações considerando combustíveis fósseis GN/carvão [41], biomassa/GN [20] e RSU/Carvão [42].…”
