Any adjustable renewable power that could improve the flexibility of the power system would be valuable. Many previous studies have suggested that Concentrating Solar Power (CSP) could make it by employing thermal energy storage (TES) .
Because sunlight has low-energy density, solar concentrators are mainly used for applications above the low range. Competing technologies include Fresnel (Tian and Zhao 2013), Parabolic trough concentrators (Xie et al. 2011), Concentrated Solar Power (CSP), and Photovoltaic (PV) Solar Panels (Yinghao 2011).
