In tower solar power generation, heliostats play a pivotal role in collecting and concentrating solar energy onto receivers for thermal conversion and storage. This study addresses two critical challenges: calculating the optical efficiency of heliostat fields and optimizing mirror installation designs. An optical efficiency model has been developed, taking into account parameters such as monthly average cosine efficiency and shadow obscuration efficiency at five time points. Utilizing a simulated annealing algorithm, a nonlinear programming model is established to determine the optimal position of the absorber tower. Heliostats are arranged in a circular layout around the tower, with installation positions and quantities determined using a polar coordinate system. An optimization model computes parameters like mirror dimensions and installation height to enhance solar energy collection efficiency. This approach minimizes energy wastage, fosters sustainable development, and drives progress in the utilization of clean energy in tower solar power generation.
