Abstract

Microgrids (MGs) dominated by power electronics interface inverters can augment distribution system resiliency. The interactions among neighboring MGs and the requirements for flexible system network reconfiguration motivate the development of dynamic MGs. To improve the distribution system resiliency in the context of dynamic MGs, this paper proposes the concept of functional fusion of secondary control levels across neighboring dynamic MGs with the integration of multiple compensation terms into the secondary controller in each distributed generator (DG). Moreover, two kinds of consensus-based algorithms with the consideration of communication delays are encompassed to calculate the average values of static and dynamic variables and thereby build an effective communications network among DGs in dynamic MGs. Finally, the effectiveness of the proposed secondary controller is validated using a 9-bus test distribution feeder.
