During the "Twelfth Five-Year Plan" period, China's power industry will invest 610 million yuan to vigorously develop power supply and power grid construction. "This will greatly promote the development of smart grids in China, and the future of smart grids has unlimited business opportunities." Sun Yucai, Party Secretary and Executive Deputy Chairman of the China Electricity Council, held the 14th International Power Equipment and Technology Exhibition 2012 recently The above indicates.
Smart grid demand is strong
As the largest exhibition event in the domestic power industry, the 14th International Power Equipment and Technology Exhibition in 2012 attracted more than 800 well-known Chinese and foreign power equipment companies from more than 25 countries and regions, including Siemens, Emerson Network Energy, Schneider and other international power equipment giants have brought leading technologies and products in the fields of power transmission and distribution equipment, power generation equipment, and smart grids.
Statistics show that since 2011, affected by the uncertain economic situation in Europe and the United States, buyers are relatively cautious and the demand for power equipment has shown a downward trend. "But emerging markets such as India, Russia and Southeast Asia have strong demand for smart grid products." Wang Zhixuan, Secretary General of the China Electricity Council, said that smart grid equipment and products have become the focus of the major manufacturers at this exhibition.
After the smart grid is fully promoted, it will have a greater impact on the market. Some experts have suggested that the implementation of smart grid transformation in China will have a huge impact on industries such as transformers, smart terminals, and network management technologies, and it can boost the national economy by at least 1-2 percentage points every year.
Sun Yucai said that building a smart grid has become the consensus of the whole society and will have a profound impact on human life in the future. The construction of smart grid has received great attention from the Chinese government and has been included in the national "Twelfth Five-Year Plan", which shows that the construction of smart grid has been promoted as a national strategy. Several domestic provinces and cities have successively initiated the formulation and planning of smart grid development action plans, and established smart grid industry alliances and industrial bases. At the same time, based on the national conditions, grid companies and related companies creatively put forward the concept of strong smart grid development with equal emphasis on "strong" and "smart", and systematically put forward the development foundation, goals, principles, technical routes and implementation plans, and gradually achieved Consensus from all walks of life, this will effectively promote the construction of China's smart grid.
Huge investment brings market opportunities
Sun Yucai said that during the "Twelfth Five-Year Plan" period, China's power industry will invest 610 million yuan to vigorously develop power supply and power grid construction, including power supply investment of 320 million yuan and power grid investment of 290 million yuan.
Sun Yucai said that such a huge investment will bring huge business opportunities for the construction of smart grids. State Grid Corporation has clearly planned to invest 286 billion yuan in intelligent construction during the "Twelfth Five-Year Plan" period. In 2012, 17 smart grid comprehensive demonstration projects, 163 charging and swapping stations and 910 AC charging piles, and 1,329 smart substations will be built, and 132 smart substations will be transformed. The construction of distribution automation systems will be promoted in 26 provincial companies. A provincial-level smart grid dispatching technical support system, popularizing and applying 37 million smart electric energy meters.
China Southern Power Grid has also made smart grid construction a top priority for enterprise development. The resulting technological progress and equipment upgrades will further promote the rapid development of China's smart grid-related fields.
Development is still constrained by technology
Although the development prospects of smart grids are widely recognized, there are still many challenges in the current development. "As far as the technical level is concerned, China's energy storage technology and complex information processing technology still need to be improved." Qi Zhiqiang of the International Cooperation Department of the China Electricity Council said.
Industry insiders pointed out that the economic efficiency of energy storage is unsatisfactory because the technology is not mature enough. The current unit cost of pumped storage is between 4000-5000 yuan, and its development is limited by geographical conditions; the cost of lithium battery capacity for energy storage is about 5 yuan per watt-hour. If the pumped storage power station is regulated on a daily basis The functional configuration of the energy storage power station will cost more than 30,000 yuan, and it also has short service life and pollution problems. In the processing of complex information, there are also certain challenges in the application of power system online simulation technology.
In addition to technology, there are institutional problems in the development of smart grids. "For example, the electricity interaction and demand-side response in smart grids all involve electricity prices, but at present, China's electricity prices are under the control of the Price Division of the National Development and Reform Commission and cannot be changed." An industry source said.
It is understood that during the "Twelfth Five-Year Plan" period, the National Energy Administration will carry out the first batch of smart grid pilot projects, including the establishment of a smart grid pilot project information database, the determination of 21 smart grid pilot projects, the study of smart grid technology application scope and standard system, Explore four items of effective economic compensation model and investment recovery mechanism.
On October 7, the General Office of the National Development and Reform Commission and the General Office of the Ministry of Finance approved the development of a major national Internet of Things application demonstration project in 7 areas including smart grids. The construction of the demonstration project will effectively improve the information collection, intelligent processing, and two-way interaction capabilities of the five major links of smart grid generation, transmission, transformation, distribution, and use, which will help promote the upgrade of China's power system to high efficiency, reliability, and greenness The company's information management level and the company's social image will have a positive impact on the construction of smart grids and have important significance for national and regional economic development.
