The invention relates to a cooling and power dispatching system for adjusting power supply and cold water, comprising a combined heat and power generation unit, a centralized heat absorption type refrigerator, an air conditioner, an electric energy meter, a fan coil, a cold water meter, a first remote centralized controller, a second remote centralized controller and a dispatching control device, wherein the centralized heat absorption type refrigerator is installed on a hot water outlet, the first and second remote centralized controllers respectively acquire the power consumption data detected by the electric energy meter and the cold water consumption data detected by the cold water meter, and the dispatching control device controls the operation of the unit, the air conditioner and the fan coil through the first and second remote centralized controllers. By acquiring the pipeline distance between a user and the unit, the cooling and power dispatching system reasonably dispatches the power supply output and the cold water output by using the pipeline distance, thus causing power load to be stabilized, achieving the effects on peak clipping and channel filling, avoiding waste of fuel resources and simultaneously causing dispatching to be more timely and accurate.
Description
technical field [0001] The invention relates to an urban comprehensive energy supply system, in particular to a method for realizing optimal control of a power system by dispatching cooling loads. Background technique [0002] Due to the development of my country's economy and the adjustment of industrial structure, the power peak-to-valley difference in the power system is increasing year by year. The difference in power peaks and valleys makes the average utilization hours of power equipment decrease, the efficiency of power generation decreases, the economic benefits decrease, and the safe operation of the power grid is greatly threatened. At present, pure condensing thermal power units are mainly used for peak regulation in power grids, but their characteristics are: insufficient capacity, huge energy consumption, and poor economy; while extraction condensing heat and power units operate in the mode of "heating power" according to relevant regulations, resulting in Ther...
