However, due to our time and energy distribution of productive forces development is not balanced, such as two-thirds of coal resources in the north, 2/3 of the hydropower resources in the southwest and northwest wind power concentrated in the land, and 2/3 more energy consumption in the Midwest. Wind power in China, solar power is mainly in the desert and gobi desert, etc in remote areas, large capacity on the local power grid in small scale, cannot use to spot, by high voltage power grid access, realize the power of long-distance transmission and XiaoNa large scope. Academician of Chinese academy of sciences, PanGuZheng just think, for energy centers and ultra-high voltage unbalanced economic center of China is necessary.
Many experts in the economic reference newspaper reporter to interview, said China's strong and intelligent network construction, cannot copy the United States and other developed countries grid pattern, but close to the development of China's social and economic development and combined with energy and characteristic of agricultura linsurance grid road of sustainable development.
Vice-president of SGC YaoJianGuo engineers, intelligent network standards, take care of the whole situation in China, and a leading role in the technical progress of energy resources and "reverse distribution, productivity layout is strong in the network must be based on the intelligent power grids, and leave the strong and intelligent is talking; and intelligent network are mainly concentrated in with electricity, it is because they have a strong network of intelligent building strong power. We are two steps and step in with electric fields, so we are absorbed the part with international standard in China, the nets. National power grid construction intelligence, emotion, but the ultimate goal and abroad is consistent, realize the flexible renewable energy and power users access two-way interaction, thereby improving energy efficiency, have low carbon development." YaoJianGuo told the newspaper reporters economic reference.
