Abstract

A multi-layer coordinated control strategy for flexible interconnected multiple microgrids（MMGs） was proposed to improve the power supply reliability of islanded MMGs and the integration of distributed energy resources（DERs）. Firstly

the topology structure and the control architecture of flexible interconnected MMGs were analyzed

and the rules for mutual power support were proposed based on the operation modes of islanded MMGs. Then

based on the rules of the mutual power support and the predicted DER output power of the MMGs

a control method for the hybrid energy storage system（HESS） under different operation scenarios was proposed. Finally

an adaptive droop control method for the flexible interconnected device（FID） was proposed. The simulation results show that the coordinated control of islanded MMGs is achieved by the coordination among the HESS and the FIDs. The proposed multi-layer coordinated control strategy takes full advantage of the control characteristics of the FID and can be adopted to realize the fast and self-adaptive dynamic mutual power support of MMGs. The power supply reliability of islanded MMGs and the integration of DERs are both enhanced with this control strategy.
