TL;DR: In this article, the authors investigated the optical layout for central receiver system (CRS), along with heliostats layout for an optical power of 400 kW to 550 kW for a close to 8 hours of operation.
Abstract: In Concentrated Solar Power (CSP) applications, the design of optical field layout and estimation of optical power received are prerequisites for its development and further implementation. Thus, the estimation of optical power is an important parameter for a given land area is an essential part for a given geographical location. In this proposed work, we investigate the optical layout for central receiver system (CRS), along with heliostats layout for an optical power of 400 kW to 550 kW for a close to 8 hours of operation. By using the ray tracing technique, we estimate amount of radiation reaching the receiver systematically and thus provides a realistic estimate of the optical power that reaches the receiver. The ray tracing carried out for a given configuration of a heliostat field provides an estimate the optical power received by the receiver for two different dimensions of heliostat, that were investigated and the area required for it are presented in this work.

TL;DR: In this article, the authors presented a simplified procedure for evaluating the annual energy produced by a defined heliostate field, based on two continuous functions: annual energy per unit of mirror with its center placed at some point; and annual average density of mirror per unit area of level terrain (which defines the field) at the same point.

TL;DR: In this article, the fundamental principles of CSP systems are discussed, including the optical processes and the ultimate limits on the extent to which solar radiation can be concentrated, and practical factors that reduce achievable concentration levels further are discussed.
Abstract: This chapter provides an overview of the fundamental principles of CSP systems. It begins with the optical processes and the ultimate limits on the extent to which solar radiation can be concentrated. Practical factors that reduce achievable concentration levels further are discussed. Mechanisms of thermal energy loss from receivers are covered. Available power cycles for electricity generation are reviewed. The second law of thermodynamics is introduced to lead into a consideration of optimization of overall system efficiency via variation of operating temperature and receiver aperture size. Performance modelling of complete systems is introduced and finally the analysis of levelized cost of energy is covered, as a metric for comparing systems, and as a tool to thermo-economic optimization in design.
