Beschreibung
Zusammenfassung:	The invention relates to a heat-pump-type power storage system based on Brayton cycle. The heat-pump-type power storage system based on Brayton cycle comprises an electric generator, at least one setof a compressor and an expander, a heat storage tank connected with the compressor, a cold storage tank connected with the expander, and an internal heat exchanger, which is connected with the compressor, the expander and a phase change packed bed energy storage mechanism separately, which are sequentially connected, wherein the heat storage tank and the cold storage tank are regarded as the phasechange packed bed energy storage mechanism. According to the system, by applying a phase change energy storage technology into the energy storage tanks (heat storage tank and cold storage tank), modifying the device structure of the system and adding a backheating process, the flexibility of a power grid can be enhanced, and not only is an electrical load balanced, but also the heat-pump-type power storage system based on
