“…The minimum production cost was 53.25$/MWh (14.73$/GJ). This production cost is similar to the one reported by Li et al, 86 but this cycle has the disadvantage of requiring much higher operating temperatures. The exergy analysis showed that the highest ExD occurred in the turbine of the ORC, comprising 41.26% of the total ExD.…”

“…From the exergy analysis, it was found that the highest ExD occurred in the condenser, turbine and regenerator, comprising 33.24%, 15.99%, and 14.72% of the total ExD, respectively. Li et al 86 reported the thermo‐economic study of a system integrated by a geothermal cycle, an ORC, and a compression refrigeration system using R1234yf, R134a, R600a, R600, R123, R601. The system was proposed to produce power and cooling.…”

“…From the thermo‐economic study, it was found that the minimum production cost was 93.87 $/GJ. This system has the advantage of being very simple and does not require high operating temperatures, but the production cost is considerably higher than other systems operating at similar temperatures 86 . Han et al 108 modeled a system including a turbine, three absorbers, and two steam generators.…”

Summary A comprehensive review of thermodynamic cycles for the simultaneous production of power and cooling is presented. The study not only actualizes the bibliographic reviews previously realized by other authors regarding cycles such as Kalina, Goswami, or modifications of them. This review additionally includes an overview of hybrid cycles and other novel cycles reported in the literature. The hybrid cycles included in the study are systems integrated by two or three conventional cycles, mainly composed of Brayton, Rankine, and ORC for power generation; and compression, absorption, and ejector cycles for cooling production. The other novel cycles mentioned are thermodynamic cycles, which considerably differ from all the others. By using internal rectification, the Goswami cycle increased its efficiency by about 5%; however, by adding diverse components, as a condenser and a subcooler, the efficiency was significantly improved due to the considerable increase of the cooling production. Organic Rankine cycles integrating absorption refrigeration cycles are, in general, the most efficient hybrid cycles, reaching thermal efficiencies close to 40% for the simultaneous production of power and cooling. If a third output was provided, as heating or water distillation, the energy efficiencies were as high as 90%. The main problem with these systems is that, in general, they are too complex and costly because of the considerable number of components. The highest exergy destruction values are reported in solar collectors when used, followed by boilers or generators, and absorbers. The lower production costs were reported with systems integrating a Brayton cycle, an organic Rankine cycle, and an ejector‐cooling cycle. The disadvantage of these systems is that they need high operating temperatures.

“…The system schematic diagram of CRFH is shown in Fig.7 (a) , which consists of an ASHP loop and a hot water loop. R134a is used as the working fluid in the ASHP cycle due to its efficient performance and environmental-friendly [50] . A heat exchanger is used to connect the ASHP loop and a hot water loop, allowing the transfer of heat from the heat pump to the tank.…”

“…For specific applications, an HDR cogeneration system that combines wind and PV energy as power sources to meet the cold, heat, and electricity demands of an independent micro-energy grid was proposed in [23]. In [24], a new type of combined cooling and power supply system was proposed in order to meet the energy demand of buildings, which can meet the seasonal cooling and power demand of buildings and maximize the utilization of hot dry rock resources.…”

Game Approach to HDR-TS-PV Hybrid Power System Dispatching

Hot dry rock (HDR) power stations have the potential to serve as an energy storage system for large-scale photovoltaic (PV) plants. For flexible operation, thermal storage (TS) power stations are required to coordinate with HDR power stations. In this study, a hybrid power system is constructed by combining the HDR, TS, and PV plants. Game theory is then introduced into the optimal dispatch of the hybrid power system. Considering HDR, TS, and PV as players, non-cooperative and cooperative game dispatching models are established and verified by a case in the Gonghe basin of Qinghai. Finally, the stability of the coalitions and the rationality of allocation of the hybrid power system is verified, and the sensitivity of critical parameters is analyzed. The results demonstrate that the overall payoff of the hybrid power system is increased by 10.15%. The payoff of the HDR power station is increased by 16.5%. The TS power station has obtained 50% of the total extra profits. The PV plant reduces the impact on the grid to obtain the priority of grid connection. Based on these results, a theoretical basis can be provided for developing generation systems based on the HDR resources in the Gonghe Basin.
