In August , Yangzhou City , Jiangsu Province was announced by the Ministry of Science and Technology as the first " smart grid special industrial base " for the National Torch Plan. In July of this year , the Shanghai Municipal Government and the State Grid Corporation of China formally signed the “Smart Grid Cooperation Strategic Cooperation Agreement†to accelerate the construction of the Shanghai Grid Smart Grid Research and Development Center of the State Grid Corporation of China.
Chinese-style smart grid
Liu Zhenya , general manager of China State Grid Corporation of China , believes that based on the characteristics of China Electric (600795) network, such as decentralization , the State Grid Corporation of China has given the definition of " Chinese-style smart grid " : UHV grid as the backbone grid, coordinated development of all levels of power grids Based on a strong power grid , it uses advanced communications, information, and control technologies to build a unified " strong smart grid " featuring information, automation, and interaction.
"After the completion of the smart grid, once the line trip, immediately dispatching system in real-time monitoring, the rapid restoration of electricity; smart grid can help you save money, as long as a home improvement on a per chip and connected to the smart socket, you can automatically sense the power grid, electricity prices changes in real time, to help you select the power of time. "State power grid Corporation of scientific research vice president Yan Hua Feng said.
The smart grid also allows the " sale of money " to be sent to the grid by installing a smart meter. In the pilot project of the Beijing Lianxiangyuan Intelligent Community , solar panels are installed on the roofs of residential buildings . When solar panels generate electricity, they can be sent to the public power grid to generate income.
Compared with traditional grids , smart grids emphasize the realization of two-way interaction between grids and users , and are cleaner , more efficient, safer, and more economical . They not only ensure the safety and economy of electricity consumption to users , but also improve the efficiency of grid equipment . Can greatly promote energy-saving emission reduction , has a broad development prospects.
According to the State Grid Corporation plans to develop smart grid in China's three stages step by step: 2009 - 2010 is planning the pilot phase; 2011-2015 was the construction phase; 2016 and 2020 is leading the upgrade stage, Completely build a unified " strong and smart grid " with technology and equipment reaching the international advanced level.
Drive economic innovation growth
Recently , with the first and second batch of centralized tendering projects named by the Smart Grid Project of the State Grid Corporation of China announced in Beijing , it indicates that the huge emerging energy industry cake of the smart grid has gradually been cut. Xiao Liye, director of Institute of Electrical Engineering Chinese Academy of Sciences believes that large radiation range of smart grid, including instrumentation, information and communication networks, electric vehicles, smart appliances, etc., but also may lead to many new industries, such as smart cities, new Financial business etc. " The planning and construction of the smart grid by 2040 will achieve an output value of more than 40 trillion yuan. "
While stimulating economic growth , through the construction of a smart grid , we will effectively improve the way users use energy , reduce the use of fossil fuels , and realize a low-carbon economy. " By 2020 , China's clean energy installed capacity will reach 600 million kilowatts , accounting for about 35 % of the country's total installed capacity , and the power generation will account for about 27 % of the total power generation. It is expected that from now until 2020 , it will use a strong smart grid as a platform . Through the joint efforts of all parties , it will promote the realization of a total of more than 10 billion tons of carbon dioxide emission reductions. †Liu Zhenya said at the Shanghai World Expo National Grid Pavilion special events day forum.
Will usher in the full construction period
The regional differences in China are relatively large . In the pilot phase, the layout of smart grid construction is more in line with national conditions. From August 2009, the State Grid Corporation of China in 26 provinces and cities have launched the construction of a total of 21 class 228 smart grid pilot projects. Among them , the second batch of pilot projects this year totaled 16 categories , involving the settlement of new energy sources such as wind power and photovoltaics , and construction of electric vehicle charging stations.
At present , the Shanghai Smart Grid Comprehensive Demonstration Project has been completed and operated . This demonstration area includes 9 demonstration projects and 4 demonstration projects. According to State Grid Pavilion Expo instructors introduced, the park many venues, including the power supply from the China Pavilion, including new energy, all venues have smart meters installed to achieve a smart power.
National Energy Board chief engineer Wu Guihui said it is preparing energy industry, "second Five Year Plan" has been the development of smart grid as an important content included.
