Recently, the first meeting of the second session of the Workers' Congress of the State Grid Corporation of China and the 2011 work conference ended in Beijing. The smart grid construction has not unexpectedly become one of the important work tasks of the State Grid Corporation during the “Twelfth Five-Year Plan†period.
2011-2015 is the phase of China's smart grid construction. At this working meeting, the State Grid Corporation of China detailed this development goal and proposed to build a strong smart grid with the characteristics of informatization, automation, and interaction by 2015. The three synchronous power grids with North China, Central China, and East China as the receivers and the northwest and northeast China power grids as the sending end have been formed. The resource allocation capability, economic operation efficiency, safety level, scientific and technological level, and intelligence level of the power grid have been comprehensively upgraded. World-class power grid.
As the year of the “Twelfth Five-Year Plan†starts in 2011, it is also the first year for the smart grid to enter the full-scale construction phase. The State Grid Corporation of China plans to tilt its investment in the grid of 292.9 billion yuan in 2011 to smart construction, and it is expected that there will be an agreement in 2011. 500 billion yuan was used for intelligent construction, an increase of 150% over the same period of last year. Among them, smart meters are still the main investment target for smart grid construction. In the next 4 to 5 years, the State Grid Corporation of China will invest 46 billion yuan in smart meter procurement, of which 50 million will be purchased in 2011, an increase of about 11% over 2010. According to the average price of electricity meter is 180 ~ 200 yuan / only calculation, smart meter investment in 2011 is about 9 billion to 10 billion yuan, accounting for about 20% of intelligent construction investment.
At the same time, in 2011, the State Grid Corporation of China will complete two pilot projects for smart grid construction, accelerate the promotion of key substations such as smart substations, distribution automation, and power-to-home, and build a number of comprehensive demonstration projects in Beijing and Yangzhou. Utilizing the advantages of the terminal power supply network, the State Grid will continue to promote the construction of electric vehicle charging facilities in 2011, and accelerate the exchange of power stations in accordance with the basic business model of “mainly changing power supply, supplementing charging, centralizing charging, and unified distributionâ€. In terms of layout and construction, it is expected that 150 charging and replacing stations will be completed throughout the year, and an electric vehicle replacement and charging service network will be established in cities such as Beijing, Hangzhou, Tianjin, Hefei, and Nanchang.
As one of the core platforms for achieving energy conversion and control in the construction of strong smart grids, at present, major breakthroughs have been made in the core technology R&D and key equipment manufacturing of smart substations in China. On January 4, 2010, China's first intelligent substation using the Internet of Things technology--220kV Xiqiao Smart Substation was put into operation in Wuxi, Jiangsu. In addition, the newly-built smart substation of the State Grid Corporation of China also includes seven intelligent substations including 110kV Sichuan Beichuan and 220kV Qingdao.
According to reports, smart substations are not only an important part of the smart grid, but also an important support for the integration of new energy sources such as wind energy and solar energy into the grid. As a key technology for connecting smart grids for power generation, transmission, substation, power distribution, power supply and dispatch, smart substations can better meet the requirements of smart grid information, automation, and interaction in terms of technology and functionality. The completion and commissioning of smart substations can significantly increase the level of equipment intelligence and equipment operation reliability, realize automation of unattended operations and equipment operations, improve the efficiency of resource use and production management, and operate more economically, energy-efficiently and environmentally. Taking the 220-kV Noyama transformer substation in Qingdao as an example, compared with an ordinary substation, the total life-cycle cost can be saved by 22.4 million yuan in accordance with the equipment life span of 15 years.
