| 摘 要： | 微电网技术能够解决分布式能源的大规模接入问题,需要解决的关键问题是如何实现多个分布式电源的协调控制;文章采用下垂控制与倒下垂控制相结合的综合控制策略,使微电网在无通信线路情况下实现并网和孤立运行2种模式的无缝切换,该控制方式提高了系统的稳定性和可靠性,实现了分布式电源的控制,最后通过Matlab/simulink验证了低压微电网系统采用该控制策略的可行性.

| Abstract: | Micro-grid technology aims at solving the problems caused by large-scale parallel operation in the grid of numerous distributed energy sources , and the key is the coordinated control. To solve this problem, a control strategy is proposed,which integrates droop control and inverse droop control and can achieve seamless switching to/from connected and islanded modes between the micro-grid and the main grid without the need of any communication facility. With this strategy, the control of the distributed energy sources may be realized and the stability and reliability of the system be enhanced. The feasibility of the control strategy to the low voltage micro-grid is verified by the simulation based on Matlab/Simulink. |
