Cloud-Edge Hosted Digital Twins for Coordinated Control of Distributed Energy Resources

This paper presents a novel approach for realizing coordinated control of Distributed Energy Resources (DERs) based on cloud-hosted and edge-hosted digital twins (DTs) DERs. DERs are playing an increasingly important role in supporting the frequency regulation power systems with massive integration renewable resources. However, due to significant differences DERs’ capability characteristics, individual un-coordinated responses from could lead less effective overall response undesirable traits, e.g. slow response, severe overshoots, etc. Therefore, coordination is critical ensure desirable aggregated response. A major shortcoming conventional centralized or distributed approaches their reliance real-time communications. addresses challenges by application DTs that can be hosted cloud edge minimize need communications, while being able achieve among The proposed DT-based validated using realistic simulation test setup, results demonstrate significantly improve thus offering support grid during contingency events.
