“…In a first approach the dimensioning as well as construction costs for a solar tower were calculated and the tower cost vs. tower height function was estimated (sbp Solar Tower Design) by designing, calculating and costing several towers, drawing on sbp's several decade long experience of designing towers and high-rise buildings [6]. The findings were compared to established tower cost vs. tower height functions (SAM [NREL] & Delsol3) [7], and the newly determined results used for power tower LCoE calculations (Tab. 5).…”

“…The total exergetic solar power input to CTR system is given by

{Ex}_{normalI} = Q_{normalI} {normalη}_{normals} = Q_{normalI} [1 - \frac{4}{3} (\frac{T_{normala}}{T_{normals}}) + \frac{1}{3} {((), \frac{T_{a}}{T_{s}})}^{4}]

where T s ≅ 5600 K is apparent black body temperature of sun and T a is atmospheric temperature. The average heliostat packing density, which is the ratio of mirror area to the field area and from the optimized ray trace analysis of shadowing and blocking, is typically in the range from 0.2 to 0.25 . The alignment of heliostats is shown in Figure .…”

SUMMARY This article presents the analytical evaluation of a central tower receiver solar thermal power plant with air‐cooled volumetric receiver using exergy analysis. The energetic and exergetic losses as well as the efficiencies of a typical central tower receiver‐based solar thermal power plant have been carried out under the specific operating conditions. The enhancement in efficiency of the plant from the variation in power input to constant power input achieved by thermal storage backup condition has been determined. It is found that the year round average energetic efficiency can be increased from 24.15% to 25.08% and year round average exergetic efficiency can be increased, from 26.10% to 27.10% for the selected location Jodhpur. The unit cost of electric energy generation (kWhe) is found to be INR 10.09 considering 30‐year lifespan of the solar plant along with a 10% interest rate. The present study provides a base for the development of future solar thermal power plants in India. Copyright © 2013 John Wiley & Sons, Ltd.

Small-Scale Solar Central Receiver System Design and Analysis

This thesis develops an analytical model of a small-scale solar central receiver power plant located at the California Polytechnic State University in San Luis Obispo, California at 35.28° N, 120.66° W. The model is used to analyze typical energy output at any time during the year. The power plant is designed to produce an output of 100 kW electrical power, and is supplemented by the combustion of natural gas. Methodologies for determining the proper size and layout of heliostats, optimal tower height, receiver size, and turbine engine selection are developed. In this specific design, solar shares of up to 73.2% and an annual average of 44% are possible through the use of a gas-solar hybrid microturbine engine. Larger solar shares are not possible due to the limited size of land (about 0.5 acres used for this project) which limits the number of possible heliostat installations. v
