For this purpose, many countries without exception look upon smart grid as future development directi

13、on of power grid 1-4. On the basis of present situation and practical condition, the development plans of smart grid in china with Chinese characteristics are proposed. The imbalance in the distribution of energy resources and the development of regional economic requires the high efficient development of energy resource in western region to satisfy the electricity demand of whole country. Besides, the limitation of environmental capacity confines conventional coal-fired thermal power in East China, which requires a new model of power supply,
