Study on the Optimal Design of Fixed-Sun Mirror Field Based on Variable Step Size Traversal Methods

Abstract

China has always made renewable energy an important part of its national energy strategy. In the flood of the times, China has carried out active research and development and innovation in tower power plant and fixed-sun mirror field technology, and has a complete solar energy industry chain. In this paper, a multivariate single-objective optimization model is established by using the geometric projection algorithm, the control variable method, and the variable step size traversal method, etc. The annual average optical efficiency parameter value and the annual average output thermal power in the known data heliostat mirror field are computed and extended to the unit area, which solves the problems of parameter design and mirror field layout setting under the condition that the variables are fixed in the known area heliostat mirror field.
