Elevating UHV to the global power Internet is a major breakthrough in the huge vision that the state grid has been advancing.
On March 30, the reporter learned from the Global Power Internet Conference 2016 that the annual governing council of Global Power Internet (hereinafter referred to as the Cooperative Arrangement) was held in Beijing. Liu Zhenya, chairman of State Grid Corporation of China, selected the chairman of the cooperative arrangement and arranged for the headquarters to be located in Beijing. Together, State Grid, Korea Electric Power Corporation, SoftBank Group of Japan and Russian Grid Corporation signed the "Northeast Asia Power Interconnection Cooperation Memorandum" in Beijing. This means that the first world arrangement and the construction of the global power Internet in the power category proposed by China have taken essential steps.
Domestic interconnection will be completed by 2020
Uhv has been gradually promoted by State Grid. With the concept of UHV upgraded to power Internet, State Grid further plans to complete the interconnection construction of domestic power grid in 2020.
According to the plan of the State Grid, global Power Internet is a smart grid with ultra-high voltage grid as the backbone and global interconnection. It is the fundamental channel for large-scale development, equipment and use of cleaning power around the world. In essence, it is "ULTRA-high voltage power grid + smart power grid + cleaning power". Ultra high voltage power grid is the key, smart power grid is the root, cleaning power is fundamental.
On March 30, According to Liu Zhenya, the construction method of global power Internet can be divided into three periods: domestic interconnection, intra-continent interconnection and inter-continent interconnection. Each period can be promoted harmoniously based on the actual situation. Between now and 2020, the key points are to accelerate the development of cleaning forces in various countries and the interconnection construction of domestic power grids. By 2030, key points will promote the development of large-scale cleaning power bases within the continent and the transnational interconnection of power grids. By 2050, key points will develop the "one pole and one grid" power base and promote inter-continent interconnection of power grids, thus fundamentally completing the global power Internet.
Under the State Council, state councilor Wang Yongze, points out that building the global power of the Internet in world politics, economy, skills, and so on various aspects of environmental protection, demand around the world, relevant parties work together to strengthen open sharing, accelerate skills and technological advance and standard, guarantee the network security, dedication, wisdom and strength to deal with human power.
According to the reporter, the World Power Agency will set up an expert working group with The State Grid to discuss uHV skills and the potential for large-scale interconnection of power grids and cleaning power networks in the future, so as to build a global power interconnection network and jointly promote global power interconnection.
"Large-scale transmission infrastructure construction is very important in addressing future power supply issues. "Getting used to renewable energy, such as solar and wind, it is necessary to plan and build grids from the ground up so that we can fully tap into the potential of global grid connectivity." According to the analysis, 40 percent of existing transmission lines are aging and facing obsoletion, so now is a good opportunity to build transmission lines and transmission infrastructure from scratch, said WPA Director General Beal.
