Distributed energy storage control method and energy storage device of distributed energy storage control method

Abstract

The invention discloses a distributed energy storage control method and an energy storage device of the distributed energy storage control method. The energy storage device comprises an energy storage container and an energy storage machine set, wherein the energy storage machine set is connected with the energy storage container through a circulation pipeline. The energy storage machine set is externally connected with a host machine. The host machine comprises at least two refrigerating machines. A control box is arranged at the upper ends of the two refrigerating machines which are connected with the energy storage machine set through energy circulation pipelines. The host machine is arranged in a machine room, wherein multiple energy storage devices are evenly distributed in a building and connected with the host machine through pipelines, the host machine conveys water to each energy storage device through pipelines after cooling the water, and then the water is directly conveyed to each unit in the building through each energy storage device. Due to the fact that energy storage and conveying operation are conducted at night in an electricity utilization trough, electricity consumption in the day time can be reduced, and power supply pressure is lowered.

Description

technical field [0001] The invention relates to a distributed energy storage control method and an energy storage device thereof, belonging to the field of energy storage cooling. Background technique [0002] Cold storage technology is to use refrigerators to cool during the low power consumption period at night when the power load is very low, and use the sensible heat or latent heat characteristics of the cold storage medium to store cold energy in a certain way. During the day when the power load is high, that is, the peak period of power consumption, the stored cooling capacity is released to meet the needs of building air conditioning or production processes. [0003] The conventional way of energy storage and function is to supply energy from a central energy storage device, and then carry out unified transmission by the central system. The cost of transportation is relatively high, and it is easy to cause energy loss during the transportation process. Moreover,...
