What is a UHV power line?

UHV power lines are high voltage transmission lines rated at voltages above 500 kV. They are typically deployed for efficient, long-distance, and bulk transmission of electricity. UHV transmission lines can reduce the cost of electricity transmission through the relocation of energy resources and improve power system stability.

Why is China developing UHV power transmission systems?

The power demand increases rapidly in China; however, the areas of huge power demands are of long distance from most areas of abundant energy resource in the country. Therefore, China put in great effort to develop ultrahigh voltage (UHV) power transmission systems to optimise its energy allocation.

Can UHV power transmission improve energy allocation in large areas?

It is concluded that China obtained mature experience in developing, constructing, and operating UHV systems and successfully realised long-distance, large-capacity power transmission, and the UHV power transmission technology has become an important measure for energy allocation in large areas. 1. 2.

Can UHV improve China's cross-regional power transmission capacity?

Conclusion and policy implications With a large number of UHV projects operational, China’s cross-regional power transmission capacity is increasing rapidly. Because of the urgent demand for safe supply, the power system benefits considerably from the suitable UHV delivery method through the optimization of UHV transmission characteristics.

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 .

How is UHV power transmission modeled?

Methodology 3.1. Method modeling of UHV power transmission in power system operation simulation In this study, UHV power transmission was modeled in two modes: stable operation and flexible operation.
