Abstract

The invention provides a hierarchical optimization method for a united cold supply system consisting of a conventional electric refrigerator and an ice storage system. The method comprises the steps of optimizing the on-state and the optimal power setting value of each cold source by adopting a mixed integer programming method according to the economic model of each cold source and the time-of-use power price policy, designing a target-coupled coordinated distributed prediction control method to better improve the dynamic performance of the system in view of the dynamic adjusting characteristic and physical constraint of each cold source, and newly optimizing the setting value of each cold source under a distributed framework, so that each cold source ensures the total load in the dynamic process and tracks the optimal refrigerating power setting value as much as possible at the same time. The method quantitatively solves the steady and dynamic scheduling problem of the united cold supply system by adopting mixed integer programming and distributed prediction control methods respectively, and provides a rational suggestion for energy management and optimization scheduling of the cold supply system.

Description

technical field [0001] The invention relates to the field of energy network scheduling, in particular to a hierarchical optimization method for a combined cooling system composed of a conventional electric refrigerator and an ice storage system. Background technique [0002] Due to the common shortage of land in large cities, high-rise buildings have become an ideal choice for urban designers in order to use limited land area to maximize urban capacity. High-rise buildings often have an independent cooling network to provide various cooling needs of the entire building. With the emergence of various emerging technologies and the promotion of the time-of-use electricity price policy, the economic benefits of the cooling system using only conventional electric refrigeration units are not satisfactory. In order to improve the economic benefits of the cooling system of high-rise buildings, multi-cooling units complement each other The system is becoming more and more common. A...
