Hybrid power management for DC microgrid cluster
Electric Power Systems Research, 2021Abstract DC microgrid clusters enhance reliability and effective utilization of resources. In this paper, a hierarchical power management strategy is proposed for two DC microgrids interconnected through dual active bridge (DAB) converter. The control hierarchy consists of droop control to ensure proportional power sharing within the microgrid, DC ...

Decentralized control of DC microgrid clusters
2017 IEEE 3rd International Future Energy Electronics Conference and ECCE Asia (IFEEC 2017 - ECCE Asia), 2017This paper explores the interconnection of multiple microgrid with “tie-line”. Tie-line control can be managed to control the power flow from microgrid and voltage at respective microgrid buses at the point of interconnection. Formation of such DC microgrid cluster ensures higher reliability of power supply and flexibility to manage distributed energy ...

Optimal Coupling of Multiple Microgrid Clusters
2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia), 2019Large remote areas may consist of multiple microgrids (MG), each owned and operated by a different owner (operator) in standalone mode. However, they can be coupled provisionally to support each other during overloading or excessive generation by renewables.

optimized Dispatch of Multi-energy Microgrid Clusters
2020 12th IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2020The joint scheduling of multi energy micro energy network group can effectively absorb the residual heat of electricity in each sub micro network through the characteristics of energy substitutability and multi-agent interaction. However, the complex relationship of multi energy interaction brings difficulties to joint scheduling.

Distributed Tertiary Control of DC Microgrid Clusters
IEEE Transactions on Power Electronics, 2016A distributed control method is proposed to handle power sharing among a cluster of dc microgrids. The hierarchical control structure of microgrids includes primary, secondary, and tertiary levels. While the load sharing among the sources within a dc microgrid is managed through primary and secondary controllers, a tertiary control level is required to
