Optimization of Tower Solar Heliostat Field Layout Based on Differential Evolution
In order to improve the radiation reflection efficiency and power generation performance of tower solar energy,it is necessary to optimize the layout of the heliostat field.Using the method of daily average optical efficiency,the average cosine efficiency,atmospheric attenuation efficiency,truncation efficiency,and maximum optical efficiency were calculated and analyzed,providing evaluation indicators for the subsequent arrangement and optimization of heliostat fields.Taking the Gemasolar tower power plant in Spain as an example,the optical efficiency and reliability of the arrangement method were verified to be high by using a dense campo arranged mirror field as the initial mirror field.Using Differential Evolution to optimize the mirror field,the annual average comprehensive efficiency of the mirror field increased from 56.99%to 59.03%,an increase of 3.58%,which proved the effectiveness of the method.
