For the current situations that electrical power operation environment is more complex, the power organization reformconstantly, the electricity market is formed step by step, the current electrical equipment is outdate, and for the so many problems that lowenergy efficiency, poor power quality, less interaction between customers and power grid company, this paper defines the smart grid that is suited to China's power grid situation, and summarizes five features for the smart grid such as self-healing, interactive, optimization,compatibility, integration and the differences between smart grid and traditional grid, then introduces the four systems of smart grid and two foundations before building the smart grid, and finally concludes that smart grid is the inevitable result for the economical and technological development.

Although the measures such as the simulation method with detailed generator model in which the dynamic behavior of exciting system is taken into account and installing power system stabilizers in main generators of Northeast Power Grid were adopted, it was still unable to effectively verify the reasonableness of parameter setting of PSS as well as its integrated matching result, and there was not enough scientific foundation for the selection of power grid model, especially load models. Moreover, it was hard to make accurate quantitative analysis, even though the qualitative analysis, on the close extent of selected models to actual operation of power grid.
