Coupling carbon capture thermal power generation system and zero-carbon zero-output operation method

The invention relates to the technical field of energy, in particular to a coupling carbon capture thermal power generation system and a zero-carbon zero-output operation method. The carbon capture module is suitable for carbon capture during and/or after fuel combustion of the power generation module; the carbon capture module comprises power equipment, regeneration equipment and a first storage tank; the first storage tank is connected with the regeneration equipment to store the regenerated working medium; energy required by regeneration of the working medium can be supplied by the power generation module at the electricity consumption trough, so that the power generation module can maintain the lowest stable combustion state under the condition of meeting the on-grid energy required in the electricity consumption trough; a working medium required in the peak period of power utilization can be provided by the first storage tank; therefore, the power generation module does not need to be started and stopped
