Structural design challenges and implications for high temperature concentrating solar power receivers

Bipul Barua et al.

Summary: High operating temperatures, diurnal cycling, and high operating stresses pose challenges for concentrated solar power (CSP) receivers. Design rules in the ASME Boiler and Pressure Vessel (B&PV) Code were not intended for CSP components. This paper reviews the applicability of design rules in the ASME B&PV Code for designing high temperature CSP receivers and finds similarities with the loading conditions of CSP receivers in Section III, Division 5 of the code. It also applies the proposed design rules to an external tubular receiver design and discusses lessons learned and mitigation actions to improve receiver design life.

Geometric optimization of a solar tower receiver operating with supercritical CO2 as working fluid

Bruno S. Emerick et al.

Summary: This study proposes using supercritical carbon dioxide as the working fluid for a cylindrical solar tower receiver and models the receiver to consider various parameters affecting its efficiency. The results show that the mass flow rate of the cooling fluid and the number of plates greatly influence the receiver's efficiency, and by varying the number of plates, the design that maximizes efficiency can be identified.

Thermal stress durability and optical characteristics of a promising solar air receiver based black alumina ceramics

Dina H. A. Besisa et al.

Summary: This paper presents a detailed study of the optical performance and thermal stress durability of black Al2O3/CuO ceramics as solar receiver materials. The results show that adding and increasing the content of CuO can transform alumina into a solar absorber material with high absorptivity in the UV-VIS-NIR spectrum. Thermal stress analysis demonstrates outstanding stress durability and uniform heat distribution in the different ceramics. Therefore, black Al2O3/CuO ceramics can be considered ideal solar absorber materials with high sustainability and durability at high temperatures.

Kang-Di Lu et al.

Summary: This article proposes a novel three-stage dynamic false data injection attack (DFDIA) model in cyber-physical power systems (CPPS) by considering potential dynamic behaviors. It formulates the designing DFDIA as two constrained single-objective optimization problems and presents two versions of constrained differential evolution as solvers. It also proposes an interval state forecasting-based countermeasure to detect the established DFDIA and demonstrates their feasibility and effectiveness through extensive simulation experiments on IEEE bus systems.

Numerical study on the start-up strategy of cylindrical tubular receiver filled with nickel foam

Ze Wu et al.

Summary: In this article, a numerical model is developed to analyze the thermal characteristics of a cylindrical tubular receiver filled with nickel foam (CTRNF) under different start-up strategies using N2 and Ar as the working medium. The results show that the duration for different start-up strategies range from 1032 s to 2189 s as the outlet temperature reaches 1200 K. The consumption of Ar working medium decreases significantly for semi-cold, semi-hot, and hot start-up strategies compared to the cold start-up strategy. However, the hot start-up strategy results in higher maximum equivalent stress in the CTRNF, highlighting the need for accurate temperature monitoring.

Transient simulation of a control strategy for solar receivers based on mass flow valves adjustments and heliostats aiming

Jesus Garcia et al.

Summary: This paper proposes a control strategy for solar central receivers that aims to maintain the receiver operating below its design limit by controlling the outlet fluid temperature and considering the heliostats' aiming points location. The strategy utilizes intermediate flow valves to reduce time delay and incorporates feedback and feedforward loops to account for DNI measurements. The proposed strategy achieves significant improvement compared to conventional single-loop temperature control.

Studies on thermal-hydraulic characteristics of supercritical CO2 flows with non-uniform heat flux in a tubular solar receiver

Xiaokai Liu et al.

Summary: In this study, the thermal-hydraulic characteristics of SCO2 in a vertical receiver tube under non-uniform heat-flux conditions are numerically studied. The non-uniform distribution of the axial heat flux leads to an increase in the overall heat transfer coefficient and severe local heat transfer deterioration. The buoyancy effect changes the flow structure, resulting in heat transfer deterioration, while downward flow can alleviate heat transfer deterioration and reduce wall temperature gradient.
