TL;DR: In this article, the authors described the technologies in question and their systems, summarizing the research achievements of some Chinese and foreign academics and comparing their advantages and disadvantages, and concluded that the tower and trough type technologies are most suitable for large-scale solar energy thermal systems.
Abstract: The research on large-scale solar energy-based thermal power generation technologies in China is still in its infancy but in foreign countries it has been going on for many years.The authors have described the technologies in question and their systems,summarizing the research achievements of some Chinese and foreign academics and comparing their advantages and disadvantages.The tower and trough type technologies are most suitable for large-scale solar energy thermal systems.Due to its relatively small power output,the dish type is applicable for distributed energy source systems.Other systems are still in their experimental and research stage.Among the above,the integrated technology of the tower type and the vacuum heat absorption tube technology of the trough type will be the focus for future research.

TL;DR: In this paper, a short overview of the state-of-the-art of Concentrating Solar Power (CSP) including the status in China is presented, and a blueprint for China's CSP development is elaborated based on China's 13th 5-year program and previous success factors in PV and wind power.
Abstract: China is the world leader in several areas of clean energy, but not in Concentrating Solar Power (CSP). Our analysis provides an interesting viewpoint to China's possible role in helping with the market breakthrough of CSP. We present a short overview of the state-of-the-art of CSP including the status in China. A blueprint for China's CSP development is elaborated based on China's 13th 5-year program, but also on China's previous success factors in PV and wind power. The results of this study suggest that China could play a more prominent global role in CSP, but this would require stronger efforts in several areas ranging from innovation to policies.

TL;DR: Based on the combination of the first and second laws of thermodynamics, a new humid air turbine cycle that uses low- or medium-temperature solar energy as assistant heat source was proposed for increasing the mass flow rate of humid air as discussed by the authors.
Abstract: A new humid air turbine cycle that uses low- or medium-temperature solar energy as assistant heat source was proposed for increasing the mass flow rate of humid air. Based on the combination of the first and second laws of thermodynamics, this paper described and compared the performances of the conventional and the solar HAT cycles. The effects of some parameters such as pressure ratio, turbine inlet temperature (TIT), and sollar collector efficiency on humidity, specific work, cycle's exergy efficiency, and solar energy to electricity efficiency were discussed in detail. Compared with the conventional HAT cycle, because of the increased humid air mass flow rate in the new system, the humidity and the specific work of the new system were increased. Meanwhile, the solar energy to electricity efficiency was greatly improved. Additionally, the exergy losses of components in the system under the given conditions were also studied and analyzed.

TL;DR: In this paper, a sectional lumped parameter model of the molten salt receiver, whose prototype is Solar Two located in USA, is established by the space discretization of the heat tubes according to the law of conservation of energy and mass.
Abstract: The receiver is an important part for photothermal conversion in the solar tower power station. Thus, modeling and simulation of the receiver is extremely significant for the safety and steady-operation of the plant. The sectional lumped parameter model of the molten salt receiver, whose prototype is Solar Two located in USA, is established by the space discretization of the heat tubes according to the law of conservation of energy and mass. The validity of the model is verified through the comparisons between the test results of the receiver in Solar Two plant and the simulation results. The heat transfer characteristics of the receiver in the cases where the inputs change and the received energy distribution isn't uniform are analyzed by the transient simulation, which can provide the foundation for the investigation of the aiming points strategy and safe operation of the station.
