Modelling strategies for porous structures as solar receivers in central receiver systems: A review
Renewable and Sustainable Energy Reviews, 2019Abstract An international effort is being made to contribute to greener electricity production. Solar Thermal Electricity (STE) has emerged as the favourite candidate due to the advantages associated with it such as dispatchability, maturity and scalability. Particular interest is raised by Central Receiver Systems (CRSs) due to their ability to work

Volumetric receivers in Solar Thermal Power Plants with Central Receiver System technology: A review
Solar Energy, 2011Abstract Deployment of the first generation of grid-connected plants for electricity production, based on Solar Thermal Power Plants with Central Receiver System technology using large heliostat fields and a solar receiver placed on the top of a tower, is currently being boosted by the first commercial plants in Spain, PS10, PS20, and Gemasolar ...

Efficiency determination of tubular solar receivers in central receiver systems
Solar Energy, 2016Abstract This paper describes a method for the efficiency determination of a cavity receiver using the example of the solar hybrid gas turbine system SOLUGAS. Major focus is given on the improvement of a new approach of the solar flux density determination based on a measurement-supported simulation technique where an acceptable uncertainty of the ...

A 200kW central receiver CPV system
AIP Conference Proceedings, 2015Raygen Resources has recently completed a Central Receiver CPV (CSPV) pilot plant in Central Victoria, Australia. The system is under final commissioning and initial operation is expected in late April 2015. The pilot demonstrates a full scale CSPV repeatable unit in a form that is representative of a commercial product and provides a test bed to prove

Robust optimal aiming strategies in central receiver systems
Renewable Energy, 2020Abstract A central receiver system is a power plant that consists of a receiver mounted atop of a central tower and a field of adjustable mirrors called heliostats. The heliostats concentrate solar radiation onto the receiver where a fluid is heated to produce electricity in a conventional thermodynamic cycle.

The 500 kWe CRS plant has a north field of heliostats directing reflected solar energy to a tower mounted receiver. Thermal energy from the receivers is piped to a hot storage tank and then to a steam generator which produces superheated steam. This superheated steam is fed to a steam motor to produce mechanical energy to drive an electric generator ...

Estimating Atmospheric Attenuation in Central Receiver Systems
ASME 2012 6th International Conference on Energy Sustainability, Parts A and B, 2012Atmospheric attenuation loss between a heliostat field and receiver has been recognized as a significant source of loss in Central Receiver System. Methods that can improve estimation of attenuation loss using available measurements will be useful in reducing uncertainty in estimation of CSP plant production, particularly in locations and climates that

Central serous chorioretinopathy in patients receiving systemic corticosteroid therapy
Canadian Journal of Ophthalmology, 2005Central serous chorioretinopathy (CSCR) is characterized by a serous detachment of the neurosensory retina or the retinal pigment epithelium (RPE), or both, at the posterior pole. The etiology and pathogenesis of this disorder are still unknown. Several hypotheses have been proposed, including increased permeability of the choriocapillaris, defects in ...

Control of Central Receiver Systems
2012This chapter deals with modeling and control problems associated to thermosolar plants with central receiver system. All the components of a typical installation are explained, including the collector subsystem, the receiver, storage and control system. The chapter next describes simulation models for the main subsystem. The heliostat offset correction

Comparative Performance Assessment For Central Receiver CPV Systems
AIP Conference Proceedings, 2011A Central receiver Concentrating PV (C2PV) system has the potential to be the optimum solar energy generation system for utility scale because it combines the high efficiency of CPV with the low cost of a heliostat collector. Due to the off axis nature of a heliostat central receiver concentrator a cosine efficiency loss is incurred and, unlike ‘normal’
