Smart grid will promote energy **

The “State Grid Smart Grid Innovation Project” project submitted by the State Grid Corporation of China was awarded the 2014 National Science and Technology Progress Award. It is understood that since 2003, the State Grid has obtained 46 national science and technology awards, including one special award and six first prizes. The rank and number of awards rank at the forefront of the central enterprises, which indicates that the State Grid’s scientific and technological innovation strength has been significantly enhanced. Innovation results have been highly recognized by all sectors of society.

Smart grid will promote energy revolution

According to reports, the smart grid can greatly enhance the ability of the grid to accept new energy sources, achieve a wide range of resource allocation, and meet the diversified electricity demand of customers. It has become an inevitable choice for countries in the world to promote economic development and ensure energy security. The State Grid operates the world's largest and most complex power grid, which is related to the country’s economic lifeline and energy security. It is the company’s historic mission to seize the high ground of power grid technology, realize the transformation of power grid development mode, and support China’s energy structure adjustment and utilization efficiency improvement. To this end, State Grid officially launched a strong smart grid construction in 2009.

State Grid believes that smart grids are highly integrated with strong grids and intelligent technologies, with UHV grids as backbone grids and coordinated development of grids at all levels, and modern grids featuring information, automation, and interaction. Compared with traditional power grids, smart grids can adapt to large-scale access to new energy sources, improve Power Supply reliability and power quality, and increase equipment utilization. Information is more integrated and user-friendly.

The smart grid will promote the energy supply revolution. The smart grid will be based on new energy generation technologies and large-scale energy storage technologies. It will promote the transformation of energy development from fossil energy to clean energy, and promote the energy production model from centralized production to centralized production and distribution. The shifting of production to parallel shifts will enable energy to be optimally allocated from a local balance to a wide range of configurations and a balanced shift across a wider range. Smart grids promote changes in energy consumption patterns. Only smart grids based on information network technology and intelligent control technologies can adapt to energy consumption. New changes...

Achieve cross-fusion of multiple advanced technologies

Therefore, the smart grid is a large-scale system engineering involving multiple fields and industries. It is within the scope of its research to use smart electricity meters that are used by customers alone, and smart grid dispatch control systems that cover the entire grid. It is understood that when the State Grid started the construction of a smart grid, related technology research is in its infancy, no successful experience is available, standards are not perfect, and key equipment is lacking.

To this end, the State Grid, in line with its own characteristics, deepened the implementation of the "first-rate and four-biggest" scientific and technological development strategy, comprehensively promoted the construction of systems, mechanisms and platforms, gave full play to the advantages of group operation, systematically optimized scientific and technological resources, and established a world-class innovation system, directly under the scientific research. Units, directly subordinated industrial units, provincial scientific research units, overseas R&D institutions, and external science and technology resources, five types of innovative entities, have their own advantages and work collaboratively to solve problems.

The first-class innovation system generates first-rate innovation results. Up to now, the State Grid has completely broken through the core technologies of smart grids from various fields of technology, from power generation to electricity use, and promoted the transformation of China's power grid technology from a "follower" to a "leader" in the world, accumulating such things as national wind and solar energy storage. Demonstration projects and other 32 categories of 305 smart grid pilot projects, the world's largest construction scale, the highest level, the fastest and most complete variety. At the same time, it strengthened the close cooperation with domestic equipment manufacturing companies and jointly completed the development of nearly 200 smart grid key equipments, such as flexible DC valve and new energy power forecasting system, and developed a "China-made wisdom" and "Chinese creation". the road.

In addition, State Grid has also participated in the preparation of 21 international standards for smart grids, which has significantly improved its international status and influence. It has already had a lot of say in the international smart grid field.

Completely build a strong smart grid in 2020

State Grid said that in the future, it will continue to promote technology research in areas such as UHV transmission, new energy use, and large power grid security, and actively build a global energy Internet to serve the sustainable development of the economy and society.

According to the relevant plans, the “12th Five-Year Plan” smart grid construction targets: The power generation side, basically solve the technical problems of new energy grid integration, support the national planning goals of 100 million kilowatts of wind power and 35 million kilowatts of solar energy; the grid side, smart substation coverage rate More than 30%, the average power cut-off time of key city users fell to 1.5 hours, the average power cut-off time of users in the core area fell to less than 15 minutes; on the power consumption side, 340 million smart energy meters were promoted and applied to the development goal of 500,000 electric vehicles in the country. Basic equipment protection.

By 2020, the State Grid will fully build a strong smart grid. On the power generation side, it will support the national plan for 200 million kilowatts of wind power and 50 million kilowatts of solar energy. New energy will account for more than 10% of the total installed capacity of power generation. On the grid side, smart substations The coverage rate is over 65%, and the average power cut-off time of users in key cities is within 15 minutes; on the consumer side, full coverage of smart energy meters is achieved, and the scope and depth of intelligent two-way interactive services are expanded to support the development target of 5 million electric vehicles in the country. achieve.
