Background

The water pumping and energy storing power station is provided with a water pumping and power generating unit, and can pump water and generate power. In daytime and the first half night, the reservoir discharges water, and the high-water-level water passes through the dual-purpose unit, and at the moment, the dual-purpose unit serves as a generator to convert mechanical energy of the high-water-level water into electric energy and convey the electric energy to a power grid. The problem of insufficient power during power utilization peak is solved; and at the latter half of the night, the power grid is in a low electricity consumption valley, electric energy cannot be stored in the power grid, at the moment, the dual-purpose unit is used as a water pump (the dual-purpose unit can rotate reversely), the redundant electric energy in the power grid is utilized to pump water with a low water level to a high water level, and the water is injected into a high water level reservoir, so that the redundant electric energy in the power grid is converted into mechanical energy of the water to be stored in the reservoir when the power consumption is in the valley. When the electricity consumption peak is reached, the reservoir discharges water, and the mechanical energy of the water is converted into electric energy through the generator and is transmitted to the power grid. The water in the reservoir is used for multiple times, and the water is combined with two units to complete multiple energy conversion. The high-water-level reservoir stores a large amount of low-water-level water, which is equivalent to storing redundant electric energy in a power grid, and solves the problem that the electric energy cannot be stored. Because the electricity prices of the electricity consumption peaks and the electricity prices of the electricity consumption valleys are different, the electricity price of the electricity consumption peaks is high, and the electricity price of the electricity consumption valleys is low, so that the economic benefit of the water storage power station is greatly improved.

The current energy storage battery station mainly stores energy through an energy storage battery cluster, the energy storage battery cluster is generally installed and fixed in an adaptive heat management device, but when the current energy storage battery cluster heat management device is used for assembling the battery clusters, the batteries are generally fixed one by one through bolts to complete the assembly of the whole battery cluster, more manpower and material resources are required to be consumed, and the current energy storage battery cluster heat management device lacks a buffer structure for the batteries and is easy to damage due to local vibration when encountering large-scale impact.
