A Review on Microgrid Technology Containing Distributed Generation System

Widespread application of distributed generation systems (DGS) will bring about new opportunities and challenges to power grid operation, control and electricity market. The microgrid technology that integrates DGS, energy storage element and loads will be an effective approach to solve the interconnection of large-scale DGS with power grid. In this paper the concept relevant to microgrid, present research situation and advancement of microgrid technology in other countries are presented in detail; the features and superiority of microgrid technology in operation, control, protection and economy are overall expounded. Combining with the feasibility and economy of microgrid technology, the development prospect and research direction of microgrid technology are analyzed in depth, and it is pointed out that the microgrid can provide more reliable power supply for sensitive consumers under islanded operation.
