Equipped with electric field has become one of the key control network reconstruction
Smart distribution grid, power quality, asset life cycle management, distribution network fault, distributed energy and micro-grid... These keywords appear in China gradually into the smart grid construction, in energy saving and environmental protection under the call, the word frequency may be higher.
The smart grid is the focus of our country "1025" planning, through the highly integration of modern technology, improve the level of intelligent power grid operation control. It is understood, by the end of 2015, China will initially formed in UHV as the backbone of the strong and smart grid operation control and interactive service system, the basic realization of friendly access and coordinated control of wind power, solar power and other renewable energy.
In smart grid with electric field, also known as intelligent distribution network, the transmission and equipped with comprehensive coverage and power market, including smart grid one or two system, and not necessarily a sequence of contact, both from top to bottom, can also carry on research and implementation of from bottom to top.
China's smart grid construction showed the following characteristics:
1, the smart grid and even some only and the matched electrical;
2, smart grid, transmission and distribution is the two-way flow of each node between power and information, solve the two-way interaction between supply and demand is preferred.
3, the global common concern and participation, equipped with electric field of technology innovation of smart appliances and intelligent power switching equipment emerging
Smart grid 4, based on the traditional network developed, large quantity and wide distribution, which can optimize the investment by making full use of the existing system, acquisition, high price.
According to these characteristics, suggestions, Prof. Yu Yixin of Tianjin University the development of smart grid in China put forward his view, the smart grid security must be guaranteed, avoid a collapse of the system; the retention of the highest permeability retention of distributed power supply; power market advanced, including asset management, equipment and other issues.
To practice the new concept, new technology of distribution system development, promote the distribution system more large-scale development, cannot do without basic research and development, the use of more cannot do without high-tech, but only stay in the theory stage but will not make the smart grid in China has made considerable progress, but with practice, summing up the experience in practice, to let the smart grid really take off.
