The invention discloses a quick regulation and control system for output of a photovoltaic power station on the basis of cold-heat-power joint production. The quick regulation and control system is characterized in that the photovoltaic power station is provided with a hot reservoir and a cold reservoir, a refrigerating plant is mounted on the cold reservoir, a radiating pipeline which is communicated with the hot reservoir and the cold reservoir is arranged on a photovoltaic module rear panel, outlet water of the cold reservoir accesses a water inlet of the radiating pipeline, and outlet water of the radiating pipeline accesses the hot reservoir. The quick regulation and control system has the advantages that natural supply and demand difference between the output of the photovoltaic power station and load demand can be restrained by the quick regulation and control system, increase of network loss and waste of resources due to remote power transmission or discarding when supply exceeds demand can be prevented, a means for quickly regulating the power generation capacity can be provided when the supply is less than the demand, accordingly, waste of the light resources can be prevented to a certain extent, partial hot water demand of the power station and surrounding facilities can be met, and effects of comprehensively utilizing energy can be improved.
