摘要
At present distributed generation is becoming a hot research. In this paper, the major distributed generation technologies and the development trend are introduced. The key technology of grid-connected distributed generation system: micro-grid technology, is described. The proposed micro-grid technologies mainly include operation control such as the control problems between various micro-sources, switching process in micro-grid connection/isolation operating state, load classification principles and methods in islanding, and advanced energy management and optimal operation of micro-grid. Further, the development trend of grid-connected distributed generation technology is proposed, which is the distributed hybrid energy system and smart micro-grid in the framework of smart grid. DC-AC dual bus architecture of distributed hybrid energy system will be presented, which achieves the two-way flow and control of electric energy between large electricity network and distributed generation system. The power infrastructure and the information infrastructure of smart micro-grid will be given, and the key technical problems are pointed out.
