National demonstration standard for energy storage power stations

Where is national wind & solar energy storage & transmission demonstration project located?

demand, which calls for effective allocation of the resources. National Wind and Solar Energy Storage and Transmission Demonstration Project is located in Bashang area within the territory of Zhangbei County and Shangyi County, Zhangjiakou, Hebei Province. It’s 20km from Zhangbei County, about 50km from Zhangjiakou and around 200km from Beijing.

What happened at China's first national demonstration project?

At 10:00 AM, the plant was successfully connected to the grid and operated stably, marking the completion of the construction of the first national demonstration project of compressed air energy storage in China in accordance with the commercial power station standards.

What is the basic configuration power for energy storage?

Simulated calculation reveals that the basic configuration power for energy storage is ~ 20MW and the capacity is about 90MWh. Through comparative analysis on energy storage systems of the three types of cells in terms of technical risks, technical reasonability and technical flexibility, they have advantages of their own in properties.

Which energy storage system is best?

But in our project, we found that the energy storage system of the lithium-ion cell is the best regarding the overall performance, followed by that of the sodium-sulfur cell; that of the electrochemical flow cell is relatively poor. The power and capacity configurations can guarantee the application in Phase I project.

How energy storage system improves access capacity related to wind-solar combined power generation?

Energy storage system improves access capacity related to wind-solar combined power generation from three aspects. Smooth fluctuation of combined power generation, enhanced controllability and reduced reserve capacity. Simulated calculation reveals that the basic configuration power for energy storage is ~ 20MW and the capacity is about 90MWh.

How important is energy storage stabilization?

Research indicates that the smaller the wind to PV ratio is, the more significant the energy storage stabilization can be; when energy storage capacity is 20-40MW, the efficiency to stabilize fluctuation reaches the maximum; if energy storage capacity ranges 60-80MW, the stabilizing effect is optimum.
