基于分层控制的微网无缝切换研究
Research on hierarchical control in seamless transition of micro-grid
摘要
Abstract
Micro-grid consists of distributed generation( DG) , which is combined with local load and storage device, integrates the advantages of each proposed distributed generation units to reduce the impact on the grid.It can operate in islanding mode and grid-connected mode, when it is in grid-connected mode, the system works in current-mode, and outputs given power.While in islanding mode, it needs to maintain the stability of voltage and frequency of micro-grid.In view of the stratified control method, this paper proposes a new controller suitable for hierarchical control structure, and it can not only realize the smooth transformation, but also can weak the transient process effects, so the stability of system can be improved.Finally, the validity and reliability of the new controller are verified by establis-hing the experimental platform of micro-grid system.关键词
