Chen Guoguang, Chief Operating Officer of Huawei Digital Power and President of Huawei Smart PV, said that the significance of this project as an industry benchmark is demonstrated in the following four aspects: (1) It is the world''s largest energy storage project and the world''s largest off-grid energy storage project.
As of late 2020, China has 14 UHV alternating current (UHVAC) lines and 16 UHV direct current (UHVDC) lines in operation. [For UHVAC data, contact Energy Iceberg for more info.] Collected by Energy Iceberg: UHVDC
China is the world''s top UHV (ultra high voltage grid) builder with 14 UHVAC and 16 UHAVDC in operation (2020/11). Renewable could benefit.
UHV transmission technology can optimize resource allocation and solve the problem of power energy shortage: on the one hand, it can reduce the land resources occupied by power grid laying and reduce the number of transmission lines as much as possible; on the other hand, it can reduce input costs, increase power supply, and alleviate the

ABSTRACT. In this paper, the features and energy storage technologies for smart grid are expounded. The performance characteristics and the state-of-the-art in energy storage technology including pumped hydroelectric, compressed air, flywheel, superconducting magnetic, supercapacitor, battery, and other important energy storage technology are summarized.
In the future, a strong smart grid can help to tackle issues like power curtailment and power imbalance in China, and furthermore prepare for an inter-continental Global Energy Internet. Smart grid will grow mature as ultra-high voltage (UHV) power transmission networks are well-developed and information communication technology (ICT) are
Power grid interconnection through UHV power transmission lines optimizes the resource allocation across a wider spectrum and increases the power supply to the receiving-terminal load centers in the eastern region.
The UHV grid will aid China's plan of electrification and decarbonization, and enable integration of renewable energy by removing the transmission bottleneck that is currently limiting expansions in wind and solar generation capacity whilst further developing the market for long-range electric vehicles in China.
Ultra-high-voltage electricity transmission (UHV electricity transmission) has been used in China since 2009 to transmit both alternating current (AC) and direct current (DC) electricity over long distances separating China's energy resources and consumers.
Renewable power has been benefiting from the UHV building effort—but only recently and the positive effects are gradual. Prior to 2018, most of the grid construction was meant for transmitting thermal or hydropower from the west of China, with limited grid connections allocated to renewable power.
(2) UHV should not only be used for long-distance transmission of electricity but also provide output characteristics. The flexible-operation transmission method can reduce carbon emissions and help achieve China’s carbon peaking and carbon neutrality goals.
UHV power transmission effectively solved the disparity between energy availability in western China and demand in eastern China. Furthermore, UHV power transmission improves environmental quality by transmitting energy generated from renewable energy sources to load centers .
