Southern Grid CEO: Smart Grid yet to be Reliable and Safe
Origin:Boao Forum for Asia      Time:2014-09-08 12:18:23    Views:218597

Zhong Jun, General Manager of China Southern Grid, addressed the session "Smart Grid and Distributed Energy"on 5th September, casting doubt on the reliability and safety of the hotly debated "smart grids".

Zhong Jun warns of overzealous construction of the smart grids. He said in China at least, the most important mission of grid industry is to regulate the constructions and the distribution of the grid in a reasonable and scientific way, so that safety and reliability could be well established before any pursuits of enhancing efficiency and flexibility. As Zhong Jun introduced, about sixty to seventy percent of the total electricity usage in China today is spent on industrial productions. This number is about three times that of the United States, which is also very industrially developed. Therefore, Zhong said, the efficiency of reducing energy usage in industrial productions is the "paramount" task of the grid industry in China, and for this reason, his company, the South Grid has sent ecological experts to many major factories in China to estimate the amount their energy waste and to advice how to reduce it. Moreover, Zhong Jun stated that the geological and geographical situation of mainland China has made the western regions abundant with resources while the eastern parts highly demanding of energy. Therefore the policy that is undergoing now is to transmit resources from the west to the eastern coastal cities through high-volte grids. Thirty percent of electrical usage in Guangdong, for instance, is transmitted from the west. Thanks to this type of distant transmission, China is saving the burning of coal by more than thirty-three mega-tons per year, which is equal to saving 67 thousand tons of Carbon Dioxide.

As for the installation of the "smart grids", however, Zhong preserves a conservative attitude. He said that the new technology has no benefit for long-distance transmission and can only possibly work better on short distances in the cities. Moreover, there is actually no mature smart grid system in the world complete as an example, so the safety and reliability of this new idea is still unknown. If applied broadly, there will be a great risk of danger for cities. "The traditional technologies still need to be used", as Zhong concluded, "but we do need to get ready for the establishment smart grid and other conceptually more effective technologies as soon as possible".
