ABSTRACT

By employing the discretization principle, ray tracing method, and coordinate system transformation technique, this paper has made significant advancements in optimizing heliostat field parameters. Through a comprehensive examination of the optical efficiency of the heliostat and utilizing genetic algorithm, systematic optimization of the heliostat field parameters is conducted to seek out the optimal solution. Firstly, it is essential to clarify the optimization criteria, which include the position coordinates of the absorption tower, size of the heliostat, installation height, number of heliostats, and their respective positions. To address multiple constraints effectively, an objective function is formulated based on the annual average thermal power output per unit mirror area. The position coordinates of absorbers are considered separately by calculating thermal power output for both (0,0) and non-(0,0) coordinates to determine optimal conditions through comparison. After that, using genetic algorithm and MATLAB software package enables obtaining optimized parameters for the heliostat field. In this optimal scenario, the absorption tower's position coordinate is (0, 0), each heliostat measures 8m*8m with an installation height of 4; there are a total of 2172 heliostats covering a combined area measuring 139008 m2. The innovation in this research methodology lies in its comprehensive utilization of the discretization principle while accurately analyzing optical properties through the ray tracing method. Additionally, the complex structure within the heliostat field is aptly described through clever coordinate system transformations. Finally, the combination that optimizes parameters for heliostat fields is effectively searched using genetic algorithms. This provides robust theoretical support for designing light energy utilization systems.
