Optimal Design of Heliostat Field

Solar thermal power generation is a new type of clean energy technology with low carbon and environmental protection. As an energy input system in solar power tower plant, the overall efficiency of heliostat field directly determines the performance level of the whole power tower, so an effective and reasonable layout of heliostat field is the key to achieve the best performance. In this paper, the optical efficiency model of heliostat field is established by using the optical trace tracking method. Finally, an improved particle swarm optimization algorithm is designed to select the best set of parameters to find the best layout of heliostat field.
