Abstract

The invention discloses a steam energy storage device utilizing off-peak electricity and a control method thereof. The device comprises a heat pump, a conveying pump, an electric boiler, a booster pump, a storage tank and a first pressure reducing valve, and the first pressure reducing valve communicates with an external demand pipe network; the steam energy storage device is connected with a controller. The method comprises the following steps that power consumption information of an external demand pipe network area is obtained through the controller so as to control the starting time and the closing time of the steam energy storage device; heat demand information of an external demand pipe network is obtained, and water at different temperatures is provided for users through the steam energy storage device. The steam energy storage device utilizing the off-peak electricity aims at solving the problem that the starting time of an off-peak electricity energy storage device is short of scientific management and control, and electric energy is stored in the actual electricity utilization off-peak period.

Description

technical field [0001] The invention relates to the technical field of energy-saving and environment-friendly steam energy storage, in particular to a steam energy storage device using low valley electricity and a control method for the steam energy storage device using low valley electricity. Background technique [0002] With the rapid development of China's industrial modernization, the industrial power load is increasing rapidly; on the other hand, with the improvement of people's living standards, the commercial and residential power load is also increasing. In order to meet the needs of industrial, commercial and residential electricity consumption, higher requirements are put forward for the supply of electricity. Regardless of whether it is industrial electricity, commercial or residential electricity, the electricity load at night is significantly lower than the daytime electricity load, resulting in an increasingly widening peak-to-valley electricity load differenc...
