Assessment of concentrated solar power (CSP) technologies based on a modified intuitionistic fuzzy topsis and trigonometric entropy weights
摘要： Concentrated solar power (CSP) technology has shown considerable long-term growth with varying levels of peak development and stall phases over the years. More and more countries are finding CSP technology attractive for the production of electricity and other applications. CSP offers a variety of applications where solar power can be used appropriately, although the debate about which CSP technology has a better future perspective is still ongoing. This technology sector has seen a multitude of advancements and technological innovations. These improvements are primarily concerned with the design of the collectors and the related materials they are made from, the heat transfer processes, and the production and accumulation of energy. In order to assess these CSP technologies, in this paper we propose a fuzzy multi-criteria method. Then, Solar tower (ST), Parabolic solar trough (PST), Compact linear Fresnel reflector (CLFR), and Dish Stirling (DS) are evaluated using a modified intuitionistic fuzzy TOPSIS with a trigonometric entropy vector weight.

A method for experimental thermo-mechanical aging of materials submitted to concentrated solar irradiation
摘要： Concentrated Solar Technology can produce process heat, power and fuels from solar energy in the temperature range 150–1500 °C, bringing the question of the receiver ability to reliably perform over the expected lifetime. Conventional methods commonly used to assess the mechanical stability and lifetime involve in-door laboratory testing, which suffers from the fundamental inability to reproduce the real operating conditions. A previous work introduced an original experimental setup based on acoustic emission named IMPACT (In situ thermo-Mechanical Probe by ACoustic Tracking), designed for an in situ and passive characterization of receiver materials under harsh thermo-mechanical stresses. This paper proposes an original method, based on a modelling approach, to control the sample damage amplification with IMPACT, and assess its relevance through an experimental campaign on two selected materials (SiC and Inconel 625).

AIP Conference Proceedings [Author(s) SolarPACES 2017: International Conference on Concentrating Solar Power and Chemical Energy Systems - Santiago, Chile (26–29 September 2017)] - Systems approach to concentrated solar power (CSP) technology adoption in South Africa
摘要： To meet its future energy demand, the government of South Africa set up an Integrated Resource Plan (IRP) with the primary objective of determining its long-term electricity demand, and indicating how this demand should be met, in terms of generation type and timing. The IRP in 2010 presented the favoured energy generation techniques in SA, and it allocated 17 800 MW (42%) of the total energy mix in 2030 to renewable energy technologies (RETs). To achieve this target, the Renewable Energy Independent Power Producer Procurement Programme (REI4P) was launched and wind, solar photovoltaic (PV) and concentrating solar power (CSP) have been favoured mostly in the bids rolled out thus far. South Africa has been identified as one of the world’s best destinations for CSP because of the available solar resources, and a total of 600 MW of CSP had been purchased in the REIPPPP bids. However, the IRP update of 2016 threw CSP out of the future energy plans, when it gave no share to new electricity generation from it beyond 2030. This has created growing uncertainty of the future of CSP in South Africa. There is therefore an urgent need for collective efforts to present a broad and detailed value proposition in terms of present and prospects of CSP, and how it can be developed and deployed in the country to foster a lower tariff, encourage adoption, and ensure its return to the IRP. The study presented in this paper used a system dynamics approach to analyse the unique, critical and complex factors that affect the deployment of CSP in South Africa, as identified by concerned policy-makers, CSP experts, and existing studies. The result from this study shows that improved support for research is the most effective way to open new methods and ways in which the CSP technologies can be deployed, which will foster further CSP adoption in South Africa.
