Modelling of the receiver transient flux distribution due to cloud passages on a solar tower thermal power plant

Daniel Favrat, Germain Augsburger

As more and more solar tower thermal power plants are being operated, built or planned, effort is put both on the development and research to bring costs down and increase the plant efficiency. In those plants, the central receiver is one of the key compon ...

Thermo-economic optimisation of large solar tower power plants

Germain Augsburger

Given the growing number of solar tower power plants in operation, under construction and under planning, the assessment and the optimisation of their performance are required both at the energy level and the economic level. In other words, the same way as ...

From Single- to Multi-Tower Solar Thermal Power Plants: Investigation of the Thermo-Economic Optimum Transition Size

Daniel Favrat, Germain Augsburger

When considering very large single-tower heliostat fields, the attenuation and spillage losses are growing with the distance to the central receiver. Therefore multi-tower configurations are modelled and investigated to find the thermo-economic optimal siz ...

Thermo-economic Optimisation of the Heliostat Field of Solar Tower Thermal Power Plants

Daniel Favrat, Germain Augsburger

A method of optimising the thermodynamic and economic performance of heliostat field within a solar tower thermal power plant has been developed. The method includes the generation of a heliostat field given a set of design variables, the assessment of its ...

A rules of thumb-based design sequence for diffuse daylight

Jean-Louis Scartezzini

This paper proposes and validates a daylighting design sequence for sidelit spaces. Since the design sequence uses the daylight factor as a performance metric, it is aimed towards spaces that primarily receive diffuse daylight. It should be complemented by ...

Multi-objective thermoeconomic optimisation of the design of heliostat field of solar tower power plants

Daniel Favrat, Xavier Pelet

Solar thermal power plants have a large potential, particularly in the sun belt countries around the world. The objectives of this study are to identify the heliostat fields for solar tower plants with the lowest specific energy cost and to investigate the ...
