Optimizing heliostat solar power plant field design: using the golden ratio of the Fibonacci sequence

Considering the importance of achieving sustainable development and using the potential of clean and renewable energy resources, such as solar energy with the highest efficiency, this research aims to optimize the design of the Heliostat solar power plant field with a central tower using the golden ratio of the Fibonacci sequence and investigate the effect of this ratio on the designed field results. The reference pattern used in this paper is the radial staggered pattern. The field under study is located in Naypyitaw (the capital of Myanmar). In this paper, with the approach of optimizing the heliostat field design, using the equations available in the design of solar power plants, the results of the new field pattern calculated using the golden ratio are investigated. The results of this research show that using the golden ratio increases the area required for the placement of heliostats by 27%, while increasing the optical efficiency by 77%. Also, in this case, it will be possible to increase the number of heliostats by 11% without increasing the current area.
