摘要
Multi-microgrid system has high power distribution reliability, improve distributed power generations installation. This paper researches the sub-microgrid system in series and parallel system structure and design two hierarchical control schemes of multi-microgrid system in series and parallel structure. Then the functions of power management, state management and synchronous control in MicroGrid Central Controller (MGCC) are analyzed. For tie-line power control, grid-connected and islanded mode switch of multi-micro-grid system, this paper researches MGCC coordination strategy among sub-micro-grid systems of multi-microgrid system in series and parallel structure, researches method of multi-microgrid system synchronized control. According to the experimental system, a multi-microgrid system model in series and parallel structure is build in Matlab / Simulink software. Then simulation and analysis are conducted for tie-line power control and dynamic characteristics of synchronization process, in order to verify the correction and effectiveness of the control strategy.
