What is attenuation characteristics analysis based on a real pumped storage power station?

Attenuation characteristics analysis based on a real pumped storage power station The attenuation characteristics of the high-frequency pressure vibration in the pumped storage power station are analyzed in this section.

Does a microgrid energy management scheme consider the attenuation cost of energy storage?

Therefore, this paper proposes a microgrid energy management scheme considering the attenuation cost of energy storage. This scheme analyzes the power generation mode and uncertainty factors of distributed generators in detail.

How do you determine the attenuation rate of a vibration?

Thus, the attenuation rate of the vibration could be directly derived from the wave speed. For example, the wave speed of the headrace tunnel in a pumped storage power station is usually set around 1100 m/s and normally will not exceed 1200 m/s in the hydraulic transient simulation [, , ].

How can energy storage reduce the degradation cost of a battery?

Therefore, adjusting the output power of energy storage reasonably can effectively reduce the degradation cost of the battery, thereby lowering the overall operating costs of the microgrid. The same applies to agricultural and pastoral areas. Figure 12. Battery output power and degradation cost.

Why does the attenuation rate increase with increasing spring constants?

Furthermore, the attenuation rate (negative direction) also increases with the increase of the spring constants because a better bounding condition could deliver more stress and vibration energy from the shell to the surrounding rock.

What are the characteristics of large-scale energy storage?

The characteristics of large-scale energy storage and flexibility enable the pumped storage power stations to possess the ability of peak regulation, frequency regulation, voltage support, and so on in the power grids [4, 5].
