Study on smart grid and key technology system to promote the development of distributed generation

Abstract

In recent years, facing of growing pressure on resources and the environment, the inevitable choice is to improve the traditional energy efficiency and vigorously advance the renewable energy development. At the aspect of technology, distributed generation (DG) technology which deploys renewable energy sources gives an effective technical approach. With the level of penetration of distributed generation becomes higher, the challenges for future distribution systems have presented smart grid (SG), which integrate the advanced sensing technology, communication technology and automatic control technology, effectively takes advantage of distributed generation technology, achieves real-time alternation and coordinated operation, as well as performs the value and benefit of distributed generation.
