Power-cold-heat combined supply system for green hydrogen power generation and method of power-cold-heat combined supply system

The invention discloses an electricity-cold-heat combined supply system for green hydrogen power generation and a method thereof. A solid hydrogen storage and release module is used for storing and releasing hydrogen energy; a transcritical carbon dioxide heat pump module is adopted to assist the solid hydrogen storage and release module in hydrogen energy storage in a refrigeration mode, and heat and/or cold are/is supplied to the park; the fuel cell module is used for supplying power to the whole system and assisting the solid hydrogen storage and release module in releasing hydrogen and supplying heat to the park; the fixed power generation module is used for supplying power to the park and the power grid. And multi-stage and efficient utilization of energy is realized by utilizing enthalpy change in the hydrogen storage/desorption process. 本发明公开了一种面向绿氢发电的电-冷-热联供系统及其方法，利用固态储放氢模块进行氢能的存储与释放；采用跨临界二氧化碳热泵模块通过制冷方式辅助所述固态储放氢模块对氢能的存储，并且为园区供热和/或供冷；采用燃料电池模块为整个系统供电，并辅助所述固态储放氢模块对氢气的释放以及为园区供热；利用固定式发电模块为园区供电以及电网供电。利用储/放氢
