A number of brokerages recently pointed out that during the "Twelfth Five-Year Plan" period, the smart grid will be fully constructed. By 2015, the strong smart grid will be basically completed, and the key technologies and equipment will reach the international advanced level, optimistic about the smart grid segment industry leader, these companies are short-term With policy support, there is a broad prospect for development in the long run.
The "Twelfth Five-Year Plan" is a five-year comprehensive construction of China's smart grid. Great Wall Securities believes that in 2010, the key technologies and construction pilots of the smart grid will be fully developed. In 2015, the strong smart grid will be basically completed, and the key technologies and equipment will reach the international leading level. In 2020, the strong smart grid will be fully built, and the technology and equipment will be fully realized. International leading level. Guotai Junan believes that entering the 'Twelfth Five-Year Plan' will launch key projects such as smart grid and distribution network transformation, and the average annual investment is expected to return to 300 billion. Hongyuan Securities said that according to the long-term planning of smart grid proposed by the State Grid, in 2011-2015, China's UHV grid is expected to take shape, initially forming the intelligent operation and monitoring of UHV grids. China will initially build regional urban and rural smart distribution. From the perspective of the content of the smart grid, the development prospects of the electric network are fundamentally dependent on the grid demand. The current demand mainly includes three aspects: the demand for power generation of new energy, the regional dispatch of electricity and the grid. Safety and economics.
The concept of “smart grid†proposed by State Grid includes six links of power generation, transmission, substation, power distribution, power consumption and dispatching, involving rich technology and extensive investment fields. Guotai Junan believes that substation will become an important part of intelligentization. The construction of intelligent substation will become the focus. The total investment of intelligent substation (110kV and above) will be 232 billion yuan during the “Twelfth Five-Year Plan†period, with an average annual investment of 46.4 billion yuan. The intelligent substation emphasizes modularity. At present, the industry leaders such as Guodian Nanrui, Guodian Nanzi and Xuji Electric have complete sets of capabilities and can produce most of the core components of secondary equipment, and further complete the main equipment self-production and modules in the future. The supply of intelligent substations will be the mainstream trend. Guotai Junan said that the secondary equipment is recommended to pay attention to Guodian Nanzi, Guodian NARI, and Zhongyuan Huadian; the primary equipment is recommended to focus on TBEA, China Xidian and Pinggao Electric.
Hongyuan Securities focuses on three areas: new energy Internet access, intelligent substation and intelligent use of power terminals (including smart meters and charging stations). Hongyuan Securities said that in the case of rapid development of solar energy and wind energy, due to the intermittent and unstable power generation, grid access of new energy has become one of the important issues facing the smart grid. In the access of new energy sources, the primary concern is the reactive power compensation system and the energy storage equipment of the power grid. The role of reactive power compensation system (SVC/SVG) in the new energy access link is to provide reactive power at the power generation end, and the flexible power transmission technology represented by it can effectively suppress the fluctuation of the grid voltage caused by the instability of solar energy and wind energy. . In the industry standard for wind power access to be issued in the first half of next year, it is expected to make detailed regulations on the wind power online reactive power compensation system. According to preliminary estimates, the market capacity of reactive power compensation system is about 1 billion yuan on the new energy generation side. On the grid side, the reactive power compensation system can increase the transmission capacity of the transmission. Its future demand is about 3 billion yuan. .
At the same time, a new segment is worthy of attention, and that is the superconducting current limiter. Hongyuan Securities believes that with the improvement of the complexity and interconnection degree of China's power grid and the increase of power demand, the safety of power grids has become an increasingly important issue. Superconducting current limiters belong to power grid safety equipment, and their role is to limit grid faults. Short-circuit current, according to the current technical level, can limit the fault current by 30%~50%. Because of its low loss, fast response time and good current limiting effect, it will become an essential product for the future of power grid security. According to estimates by Hongyuan Securities, the market space for superconducting current limiters in the next decade will be as high as 13 to 150 billion yuan, and the domestic technology and manufacturing level have been initially established in China. It is expected that the market will be officially launched after 2012. .
