The invention discloses a photovoltaic power station output fast regulation and control method based on a Combined Cooling Heating and Power. When supply exceeds demand in a power supply area, refrigeration is conducted on water in a cold water reservoir by the usage of redundant power; when the demand exceeds the supply in the power supply area, through a backboard water-cooling heat dissipation pipeline, a photovoltaic panel is cooled, and system output can be rapidly increased by 10-25%; when there is spike type load input in the power supply area, cooling processing can be carried out by a power station in advance according to a dispatching instruction, and a power generation capacity margin is increased. According to the photovoltaic power station output fast regulation and control method based on the Combined Cooling Heating and Power, temperature characteristics of photovoltaic batteries are used for stabilizing a natural supply and demand difference between photovoltaic station output and load demands, a transmission loss increase and resource waste caused by power long-distance delivery or photovoltaic power generation abandoning when the demand exceeds the supply are avoided, when the demand exceeds the supply, a means for rapidly increasing a photovoltaic power generation capacity, at the same time, part of hot water demands of the power station or surrounding facilities are satisfied, and the comprehensive utilization effect of energy is improved.
