Thermoelectricity dispatching system and method of water source heat pump

Abstract

The invention discloses a thermoelectricity dispatching system for regulating power supply and hot water. The system comprises a water source heat pump, a thermal power machine set, a heat pump of an air conditioner, an electric energy meter, a heat radiator, a heat consumption gauge, a first long-distance integrated controller, a second long-distance integrated controller and a dispatching control device, wherein the first long-distance integrated controller and the second long-distance integrated controller collect the electricity consumption data detected by the electric energy meter and the heating and heat consumption data detected by the heat consumption gauge; and the dispatching control device controls the operations of the water source heat pump, the thermal power machine set, the heat pump of the air conditioner and the heat radiator through the first long-distance integrated controller and the second long-distance integrated controller. According to the invention, through collecting the pipeline distance from users to a heat source, the power supply output capacity and hot water output capacity of a thermoelectricity combined generation machine set are reasonably dispatched through utilizing the pipeline distance, thus the power load is leveled, the effect of peak clipping and valley filling is achieved, fuel resources are prevented from being wasted, and at the same time, the dispatching is 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 heating and 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, result...
