Smart grid following the 2010,2011, the third time this year the NPC and CPPCC is written into governmental working report of the. The report also pointed out that to develop new energy automobile development, distributed energy, improve energy efficiency and the energy transformation of the development pattern of closely related content. A smart grid is an important innovation of traditional power grid, will enhance the power function, and developed a variety of new business and commercial pattern, from many aspects to promote China's energy development mode change, ensure sound and rapid economic and social development.

     Smart grid can promote the sustainable development of renewable energy and distributed energy efficiency. Wind power, solar power will be in the long term to become our country important green energy pillar, strategic significance, however its intermittent and fluctuation to the power system security, economical, reliable operation and brought enormous challenge. Smart grid by integrating advanced information, automation, energy storage, operation control and scheduling technology, will make the power grid operation mode innovation, make power be non hydro renewable energy generation, conventional power supply and power user interaction platform, realize the global resources and information to optimize the overall configuration, thereby maximizing the power system acceptance the potential for renewable energy power generation, renewable energy and sustainable development provided important safeguard.

     A smart grid could promote the development of electric vehicle industry, implementation industry to maximize the overall efficiency. At present," pure electric driving" as China's new energy automotive technology development direction and emphasis have reached a broad consensus, intelligent charging for electric service network as a pure electric vehicle only energy supply scheme, will be in promoting industrial development and obtain the maximum comprehensive benefits to play a crucial role in. Through the smart grid to realize intelligent charging management, is the realization of electric vehicle industry is integrated benefit is the greatest change important way.

    Smart grid will effectively support energy efficiency improvement and energy saving and emission reduction. From the generation side, smart grid through the optimization of dispatching operation, one hand for generators to provide a more stable environment, and improve the efficiency of coal-fired power generation; the other can promote clean energy development and utilization is reasonable. From the network side, through the use of a large number of intelligent technology, can reduce the power transmission and transformation equipment energy consumption at the same time, improve power system transmission efficiency, reduce network losses, realizes the network side of the benefits of energy conservation and emission reduction. From the user side, the smart grid hand through the intelligent diagnosis technology to extend the demand side service, as the efficiency management to provide system solutions and intelligent control management platform; on the other hand, the smart grid will also guides a user through interaction, promoting the efficient application of intelligent electrical equipment, enhance the user can use the awareness, and promote energy change in patterns of consumption.

    Smart grid will further promote energy system to develop the intelligent. In the country to vigorously promote the integration of information technology and industrialization, promote the upgrade of industry background, with good development foundation, the smart grid will become energy industry system to realize the intelligent development of the forerunner, as energy is an important part of the system, the drive efficiency significantly.

    " Twelfth Five-Year Plan" period, the smart grid as part of the national strategies to support the development, the State Grid Corporation of strong smart grid strategy has entered overall construction phase, the prospects are very worth looking forward to. But at the national level of specific policy support system still remains to perfect, government of proposal our country to strengthen the National Smart Grid strategy research, accelerate the planning and construction of the deployment of work, has actively fiscal subsidies and preferential tax policies, the establishment of flexible pricing mechanism and demand side management mechanism, increase the key Technologies R & D investment, strengthen standard system construction and promote standards internationalization, form as soon as possible take the government as the leadership, multi-party participate actively, to promoting smart grid development in China in the new situation.
