The invention provides a combined cooling and power scheduling system for adjusting power supply and cold water. The system comprises a water source heat pump, a thermal power generating unit, a centralized heat absorption type refrigerator which is installed at a hot water outlet of the water source heat pump, an air conditioner, an electric energy meter, a fan coil, a cold water gauge, first and second remote centralized controllers which are used for collecting power consumption data of the electric energy meter and cold water consumption data detected by the cold water gauge, and a scheduling control device which is used for controlling the water source heat pump, the thermal power generating unit, the air conditioner and the fan coil to operate by using the first and second remote centralized controllers. By collecting a pipeline distance between the user and the unit, a power supply output and a cold water output of the unit are rationally scheduled by utilizing the pipeline distance, so that a power load is leveled, the effects of 'load shifting' are achieved and the fuel resource is prevented from wasting; and meanwhile, the scheduling is more timely and accurate.
