Energy storage ultra-high voltage transmission nuclear power

What is ultra-high voltage (UHV)?

Ultra-high voltage (UHV) refers to power transmission lines operating at voltages greater than 800 kilovolts (kV). The such high-voltage operation has a high capacity and manages to transmit electricity over long distances with minimal power loss.

Why is high-voltage power transmission important?

The such high-voltage operation has a high capacity and manages to transmit electricity over long distances with minimal power loss. UHV power transmission effectively solved the disparity between energy availability in western China and demand in eastern China.

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.

What are the environmental benefits of China's ultra-high voltage lines?

The environmental benefits of China’s ultra-high voltage lines are analyzed. Most UHV direct current lines can bring high environmental and health benefits. Long-distance power transmission is a very important way of energy utilization, which can achieve regional environmental benefits through the transfer of air pollutants.

How does UHV transmission technology affect energy structure in China?

Impact of UHV transmission technology on energy structure in China is investigated. UHV reduces thermal power generation and boosts renewable energy generation. UHV shifts ground-based coal transportation to power transmission in the sky. Firms' energy consumption behavior changes and shifts to electrified production.

How has UHV transmission changed the energy supply mode?

We find that the opening of UHV transmission projects has changed the energy supply mode from “coal transportation on the ground” to “power transmission in the sky,” which has caused the transformation of the power production structure and promoted the development of renewable energy in resource-rich areas.
