New technologies of active distribution network in smart grid

摘要

With the rapid development of smart grid, large amount of distributed energy resources(DER) integrate into traditional distributed network, that makes the network faces some new challenges. This paper firstly describes the practical, science and technology issues of modern distribution network, then introduces the implication of active distribution network and several new concepts. New technologies for the development of active distributed network are also analyzed. Integrated application of these new technologies will provide an extensive and far-reaching significance.
