Tower-type solar power generation, an important component of concentrated solar power generation, plays a crucial role in converting solar energy into heat energy and ultimately outputting electricity through heliostat fields and receivers. In this paper, the methodology employed in this study is introduced, which involves the utilization of relevant data to analyze and establish the corresponding efficiency model. The annual average output thermal power and the thermal power output per unit mirror area of the heliostat field are then determined using established formulas. The paper further presents the results obtained, highlighting the establishment of a nonlinear programming model by setting the objective function and optimizing relevant parameters (heliostat coordinates, number of heliostats, heliostat size, installation height, and tower coordinates). The model employs the geometric projection method to establish a shadow obscuration model, which can accurately and rapidly calculate results with a clear geometric structure. This study provides valuable insights into the optimization and efficiency of tower-type solar power generation systems, contributing to the development of low-carbon and environmentally friendly power generation technologies.
