Professor Sheng said that the smart grid construction, including wind power industry can drive group, the electric car industry group, photovoltaic power generation industries, green energy-efficient buildings and smart appliances. And new materials industries, such as photoelectric conversion materials, energy storage materials, insulation materials, superconducting materials, nano-materials will also be developed by leaps and bounds. In addition, technology driven by the smart grid construction also includes the creation of platform technology for the smart grid, integrated communications technology, instrumentation, sensing and measurement technology, advanced application software, application of superconducting technology, diagnostic technology.

From smart grid connotation, the National Network Planning and the Ministry of Science departure of key technologies, smart grid new industry is mainly concentrated in the following five areas (new industry and equipment), every aspect is a big industrial group:

1, power consumptive intermittent energy


3, grid and discharge facilities interactions
2, power of information and communications

4, the smart with electric aspect

5, the flexible power transmission technology and key components and equipment

Ministry of Science and Technology Industrial Engineering Key second five special plan, mainly by 863,973, technology support program implementation
Conventional industrial upgrading focused on ultrahigh field

From the national planning and technical status to see industrial scale

For the five new industry, current status of the technology, the international advanced indicators at the end of the Eleventh Five, four aspects of second five at the end of the international advanced indicators as well as the development of our second five target vertical, horizontal comparison, we can see China and international technology gap, the gap is the industry opportunities.

1, power consumptive intermittent energy, the first one is the simulation analysis, pre-power system models with little or no; the second is the power of prediction, it is possible to predict the size of the next day or even several days of light wind, the third run control, the fourth DC sent, at this stage in these parts of the technical level or with the United States and Europe yo certain gap; energy storage applications and finally, on the one hand to store energy during the day for use at night, but we also need to eliminate power fluctuations through storage. Until the end of the Eleventh Five, China's technology in this area or with the international advanced indicators of a certain gap. But we hope that by the end of the second five, technology in all aspects of our country are able to reach the international advanced level.

2. Information and communications grids, the main technical information platform, communication platform, information security, communications components, information processing, storage and applications, in these parts, the gap between China and international technology is great, and our goal is to second five at the end to reach the international advanced level.
3, grid and interactive aspects of charging and discharging facilities, we are mainly to do some upgrades of technology, from a cost point of China has reached the international advanced level, other parts such as reliability, durability, engineering, industry and the international advanced level, etc. level there is a gap.


4, the smart with electric aspect contains seven key components: distribution automation, power distribution equipment, smart meters, two-way interactive user, distributed power access, communication and distribution of electricity distributed function, which seven technology is smart distribution The main direction of development of the electricity industry.

3, sub-regional intelligent investment
5, the flexible power transmission technology and key components and equipment included six part: assapast devices and application of technology, large-capacity high-voltage power electronic devices monitoring techniques, power flow control and fault suppression techniques, fault current limiting technology, DC circuit breakers, MTDC technology. China's power electronics technology in the application of technology and international level difference is smaller, but still significant gaps in the device, the DC circuit breaker, especially high-pressure side, with foreign technology gap is very large.
