摘要: |
针对低压微电网中传统下垂控制难以实现多个分布式电源(Distributed Generations, DGs)按照下垂系数合理分配有功输出的问题,提出了一种基于通信网络的分布式控制策略。采用并构建了Zigbee无线通信网络拓扑结构以实现DG间的信息交互。设计了基于一致性算法的分布式PI控制器以实现多个DG的有功输出按额定比分配。最后通过仿真验证了所提方法的可行性,并表明网络延时和网络拓扑结构的变化会影响微电网系统的稳定性。 |

Abstract: |
In low voltage microgrid, it is difficult for traditional droop control to make Distributed Generations (DGs) to output active power reasonably according to the droop coefficient. Aiming at this problem, a distributed control strategy based on the communication network is proposed. Zigbee wireless communication network is employed and the corresponding topology structure is built to realize information exchanging between DGs. The distributed PI controllers which are based on the consensus algorithm are designed to guarantee the active power output of DGs to meet the requirement of rated ratios. Finally, the simulation results show the feasibility of the proposed method, and indicate that the changes of network-induced delays and topology structures will affect the stability of the microgrid system.
