In this paper, the alternate movement method is proposed to perform heliostat field layout optimization. The proposed method includes two new strategies: 1) physics-based gradient of optical efficiencies, and 2) new initial layouts with an area scaling factor. In order to derive the physics-based gradient, the optical efficiency is divided into shading/blocking efficiency and non-shading/blocking efficiency. In addition, the proposed alternate movement method performs layout optimization along alternating directions which are gradients of two efficiencies. The proposed alternate movement method is applied to two field layouts – PS10 and a field layout obtained by SolarPILOT – with two objective functions, insolation weighted optical efficiency and levelized energy cost(LEC). The results show that both objective functions are much improved compared with the original layout.
