The State Grid Corporation of China is promoting its self-developed ultra high voltage (UHV) electricity transmission technology and smart grid standards overseas, in a bid to gradually establish itself as a leading player in the international power market.
The country’s largest electricity grid operator has developed and submitted three standards in the UHV sector and one standard in the smart grid sector to the Institute of Electrical and Electronics Engineers (IEEE) for international certification, the IEEE, a leading global standards organization, said Thursday.
“It takes 18 months for IEEE to complete formulating and certifying a standard, and we already started to work on the four Chinese standards in March,” Hua Ning, office director of China Operation of IEEE, told the Global Times in an exclusive interview Thursday.
“China has developed the world’s most advanced UHV electricity transmission technology, partly because of its national conditions,” Hua said.
The majority of China’s hydropower resources are located in the western part of the country and coal mines are situated in the northwest, but a huge volume of power demand comes from the east and south. UHV transmission is a logical choice for the country to reduce transmission losses.
“If the standards get approved, more international power equipment producers will adopt the standards to manufacture equipment, and these Chinese standards could play an important role in the international market,” Hua said.
However, it will not be easy to get more countries to adopt the standards because of varying conditions in different countries, said Lin Boqiang, director of the Center for Energy Economics Research at Xiamen University.
“Few countries need to transmit electricity over such a long distance as from the west of China to the east,” Lin said.
Hua said China also has difficulties in developing smart grid standards domestically. “Local information technology and telecommunications companies do not have enough strengths and capabilities to join in standards formulation, which requires high technologies.”
