The electrical grids have become the foundation and an important part of industrialization and informatization. On the other hand, they have also kept drawing on achievements of industrialization and informatization, allowing for concentrated application of various cutting-edge technologies in grids, which greatly enhanced functions of grid systems.

(1) Smart grid is the inevitable trend of technological development of power grids. In recent years, technologies such as telecommunications, computer and automation have been extensively applied in electric grids and integrated with conventional power technologies, which has greatly promoted the development of smart grids. The application of sensor and information technologies in grids has provided technical support for system condition analysis and aided decision-making, making it possible for grids to self-heal. And mature dispatching, automation and flexible transmission technologies have guaranteed the development and utilization of renewable energy and distributed power. In addition, the improving telecommunication network and application of user information acquisition technologies have also promoted the interaction between grids and users. Thus, smart grid emerges with further development and application of various new technologies and their integration with physical grids.

(2) Developing smart grid is the inevitable choice in social and economic development. To develop, transmit and accommodate clean energy, we must enhance the flexibility and compatibility of power grids. We need to rely on smart means to increase the security defense capacity and self-healing ability of grids. Meanwhile, we must operate power grids more economically and efficiently to reduce operating costs and promote energy conservation and emissions reduction, and at the same time conduct smart control on electrical equipment to reduce power loss. The rapid development of distributed generation, energy storage technology and electric vehicles has changed the traditional mode of power supply and utilization and promoted growing integration of power flow, information flow and work flow so as to meet increasingly diverse user demands.

As electricity technologies develop, power grids take on many new features, such as self-healing, compatibility, concentration and optimization, and the changes on electricity markets in turn require higher level of grid automation and information. As such, smart grid becomes the inevitable trend of grid development.
