中央控制器协同的多微电网平滑切换与并联运行研究
Multi-microgrid Bumpless Transition and Interconnect Operation Based on Central Controller Collaboration
摘要
Abstract
This paper proposes a novel control theory and architecture based on a microgrid central controller(MGCC)and single-loop grid-forming inverters to address two key challenges:the voltage surge induced during grid-connected to islanded transitions,and the difficulty in achieving stable parallel operation among multiple islanded microgrids for lateral power support.Firstly,a mathematical model of voltage dynamics during the transition process is established.The relationship between voltage phasors and synchronized switching operations during the transition and parallel operation is analyzed.Based on the inherent physical characteristics and operational principles of grid-forming inverters,the proposed architecture is explained,and its rationality is justified.The MGCC is implemented using an embedded chip,and hardware-in-the-loop(HIL)simulations are conducted on a real-time digital simulation(RTDS)platform.Experimental results confirm that the proposed architecture can effectively manage grid-to-island transitions and flexible grid connection,while it also exhibits advantages in voltage stabilization and parallel operation stability over existing architectures.关键词
