12th Five-Year is the five year of China's energy development, is the 5 year of energy structure adjustment, energy development into the new normal, a new round of electricity to set off a wave of reform.

State Grid Corporation (hereinafter referred to as the "national grid") in the key areas of UHV, large power, new energy, smart grid implementation of a series of major technological breakthroughs, Liu Zhenya, chairman of the national grid of global energy Internet concept also pushed to the world.

Xinhua energy with you to review the China State Grid Corp "12th Five-Year" report card.

Three pay four straight UHV "operation and" four pay six straight in the construction

Energy distribution and demand imbalance, resulting in a large span of energy utilization in China; clean power, the lack of large capacity, long-distance transport channels, can not be translated into economic advantages, some areas of serious pollution. Based on such a situation, China's energy structure transformation have been imminent, be badly in need of construction of large capacity, high efficiency, long-distance UHV power grid, to achieve cross regional, long distance energy transmission and transaction, better to regulate power balance, and promote the optimal allocation of resources, to play the role of the national electricity market.

At the end of the "Eleventh Five Year" period, the state grid area only two UHV project put into operation -- 1000 kV Jindongnan - Nanyang - Jingmen special high-voltage AC pilot demonstration project and to the Xiangjiaba Shanghai + 800 kV HVDC transmission demonstration project.

Today, the national grid has been built three to four straight UHV project, four to six straight is under construction, in the construction of 17 UHV transmission line length of more than

During the period of 12th Five-Year, especially high pressure from the "test" "demonstration" to the comprehensive large-scale construction, with special high pressure as the backbone of the grid has a strong smart grid. Data show that the Twelfth Five Year Plan "period, the national grid of UHV Engineering change electric (converter) capacity of more than 2.9 million KVA (kw), the total power transmission more than 4300 million kilowatts.

Smart grid construction has made a major breakthrough

In early 2011, the smart grid construction into the national "12th Five-Year" planning framework. Five years, the State Grid independent research and development and construction of the smart grid dispatching technical support system and put into operation in Tianjin new ecological city, national scenery storage and transportation, and other smart grid demonstration project.

Smart grid extensive connection energy base, all kinds of distributed power supply and load center, in play based on grid and strong network effects and achieve around the centralized power and pan in distributed power optimized access and efficient disposal, to ensure that the distributed power flexible access and operation, to promote the new energy consumptive, more safe and reliable will be sent the new energy to the load center.

As the world's third large enterprises with flexible HVDC intellectual property rights, the company in the flexible HVDC transmission key technologies to produce a beautiful transcript. During the 12th Five-Year, the company in the study and construction of a new generation of Smart Substation on the road struggling to move forward. From the supply side to the client side, from the backbone network to smart home, smart grid construction layers.
