Thermal energy storage (TES) technology is an effective method to alleviate the incoordination of energy supply and demand in time and space intensity and to improve energy efficiency [8]. TES is usually classified into low temperature (T < 100 °C), medium temperature (100 °C ≤ T ≤ 300 °C) and high temperature (T > 300 °C) TES [9].
