摘　　要：分析熔融盐储热(间接熔融盐储热和直接熔融盐储热)技术主要设备功能和工作原理。通过国内外典型储热电站项目对比,指出塔式储热电站单位装机容量造价随时间呈下降趋势,我国项目单位装机容量造价下降明显。提出熔融盐储热电站与虚拟电厂技术结合的新型技术方案,分析其工作过程。熔融盐储热电站接入虚拟电厂具有提高能源利用效率、缓解电力供需矛盾、提升系统稳定性、降低环境污染、增强系统灵活性和经济效益等益处。The main equipment functions and working principles of molten salt heat storage(indirect molten salt heat storage and direct molten salt heat storage)technologies are analyzed.Through the comparison of typical heat storage power station projects at home and abroad,it is pointed out that the cost per unit installed capacity of tower-type thermal storage power stations shows a downward trend over time,and the cost per unit installed capacity of projects in China decreases significantly.A new technical scheme combining molten salt heat storage power station and virtual power plant technology is proposed,and its working process is analyzed.The connection of molten salt heat storage power station to virtual power plant has the benefits of improving energy utilization efficiency,alleviating the contradiction between power supply and demand,improving system stability,reducing environmental pollution,and enhancing system flexibility and economic benefits.
