Optimal design and control of heliostat for solar power generation

The purpose of this research is to optimal design and control of heliostat for solar power generation in real time. Tracking the sun and calculating the position of the sun are possible by using illuminance sensor (CdS) and Simulink program. As heat transfer from heliostat to receiver is delivered by solar radiation, configuration factor commonly utilized in radiation is applied to control heliostat. Algorithms for maximizing configuration factor between sun, heliostat and receiver in real time are programmed by Simulink. By applying the optimized algorithms, the efficiency of the solar absorption in receiver can be maximized. Simulation was performed how to control azimuthal and elevation angles during the daytime with respect to diverse distances.
