Abstract
Abstract Due to the geographical location and natural climatic conditions, solar energy has a priority in Kazakhstan among all renewable energy sources. Some regions of Kazakhstan experience more than 270–300 sunny days per year, making it possible to utilize solar energy almost all year round. In this regard, there is a need for the development and implementation of large-scale solar technology. In this study, a comprehensive review and analysis of modern solar technology structures were conducted. The primary focus of this research lies in the following tasks: developing operational modes through computer simulation, modeling the structure of the focal spot in the optical system, and exploring the potential of employing contemporary digital and computer technologies. The optimization issues and computer simulation of the operating modes of the optical system in a tower-type solar power plant are considered in more detail. A calculation scheme and a mathematical model have been developed to estimate the local values of the efficiency coefficient (η) for the use of a mirror surface of the heliostat field. The results are visually presented in the form of a map for local values of the efficiency coefficient (η) of using the mirror surface of the heliostat field in tower-type solar power plants.
