What is ultra-high-voltage (UHV) transmission?

Ultra-high-voltage (UHV) transmission systems have been used prominently in China for the power distribution of renewable energy. The flexible operation of UHV lines and its effect on production cost and carbon emissions have attracted considerable research attention.

How does UHV power transmission improve environmental quality?

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 .

Do UHV projects promote inter-regional power transmission?

UHV projects promote inter-regional power transmission but increase power-sending cities’ energy consumption (Tan et al. 2022). That is, energy consumption and carbon emissions are transferred between power-sending and receiving cities from the perspective of UHV power transmission.

What is ultra-high voltage (UHV) line?

Ultra-high voltage (UHV) line can effectively reduce transmission losses, thus making long-distance and large-scale electricity transfer possible (Yi et al., 2016). 1 Globally speaking, China is the country with the most rapid development of UHV technology.

What is UHV power grid interconnection?

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.

How effective are UHV transmission lines?

UHV transmission lines feature high transmission efficiency, long transmission distance, low line loss, and flexible power deployment. These characteristics make them effective in overcoming the market segmentation of the power supply caused by the imbalance of China's regional energy resource endowment.
