Review on the Research of Distributed Generation Technology and Its Impacts on Electric Power Systems

The distributed generation technology is at the stage of limited application now,confronting restrains from the economic efficiency,business modes and policy environments,and thus to understand these restraints and adopt effective countermeasures is a key issue for its development in a large scale.Summarizing the disadvantages of centralized power supply and the advantages of distributed power supply,and classifying the research subjects related to the distributed generation,this paper makes an overview on the various impacts from the distributed resource integrating into power grids,and its main related research fields,pointing out that how to coordinate the distributed resources and network,or to coordinate microgrid and network is an important issue to be studied and resolved in near future,and the coordination of the distributed resources and network is the basis for the application of distributed generation technology while the coordination of microgrid and network is one of the supports for the construction of smart distributed network.
