Example Embodiment
[0034] Example one:
[0035] This embodiment can be used in the peak shaving and valley filling mode of the power grid, and can also be used in large-scale storage and release of new energy electric energy such as wind power and photovoltaic power generation. At the same time, a heat exchanger is installed before the adjustable pressure matcher to further improve the working performance of the adjustable pressure matcher.
[0036] Such as figure 1 , figure 2 , Image 6 with Figure 7 As shown, in the energy storage stage, in order to increase the energy density of the air in the compressed air storage tank 113, a mode of continuous serial operation of multiple air compressors 111 is adopted. The first air compressor 111 is connected with a motor 110 in series, so that the last one The air compressor 111 outputs compressed air with high pressure parameters (for example, 9 MPa). In order to fully recover the compression heat and at the same time ensure the safe operation of all a...
Example Embodiment
[0042] Embodiment two:
[0043] Such as image 3 , Image 6 with Figure 7 As shown, this embodiment can be used in the peak shaving and valley filling mode of the power grid, and can also be used in large-scale storage and release of new energy electric energy such as wind power and photovoltaic power generation. The difference compared with the first embodiment is that in this embodiment, the configuration of the heat exchanger 210 is eliminated before the adjustable pressure matcher 310, and the compressed air flow in the compressed air storage tank 113 directly enters the compressor without being heated. Adjustable pressure matching device 310. In addition, the configuration of other parts of the energy storage system is consistent with the first embodiment.
Example Embodiment
[0044] Embodiment three:
[0045] Such as Figure 4 , Image 6 with Figure 7 As shown, this embodiment can be used in the peak-shaving and valley-filling mode of grid-connected power grid and new energy electric energy, and can also be used in the electric energy online smoothing mode of real-time grid-connected new energy electric energy such as wind power and photovoltaic power generation, which greatly improves The ability of the energy storage system to adapt to multiple functional requirements allows both the peak shaving and valley filling mode and the electric energy online smoothing mode to achieve their respective best energy storage efficiency.
[0046] In the configuration of the energy storage system, multiple air compressors 111 are configured. The first air compressor 111 is equipped with a motor 110 in series, and a clutch 112 is installed between the air compressors 111 to allow high-pressure air to be used according to the requirements of system operation. The co...
