Technical FAQs 4

What is China's first 'wind-solar-thermal-storage integration' project?

(Photo by Xu Ke/People's Daily Online) China's first "wind-solar-thermal-storage integration" ultra-high voltage (UHV) project, the Longdong-Shandong ±800 kilovolt direct current (DC) transmission project, was put into operation on May 8.

What is the new UHV line?

The new UHV line will enable the stable transmission of over 10 million kilowatts of renewable power, facilitating the coordinated flow of energy across regions. At the heart of the project is a vast energy base run by China Huaneng Group, a major state-owned power company.

What is hybrid solar PV & wind?

Hybrid solar PV and wind frameworks, as well as a battery bank connected to an air conditioner Microgrid, is developed for sustainable hybrid wind and photovoltaic storage system. The heap voltage's recurrence and extent are constrained by the battery converter.

Is SGCC's UHV line the first in China?

Yang Pengcheng, deputy director of the converter station department of SGCC's UHV Division, noted that the line is the first in China to deploy a range of homegrown switchgear, control systems, and protection equipment -- each developed with independent intellectual property rights.
