Summary: Objectives of the proposed research are to improve the observability and controllability of the distribution system specifically to improve system modeling for outage management and enhance system resiliency using controllable DER. The following technical objectives are addressed to develop the proposed architecture:

  • Objective 1 – Improving System Modeling for Outage Management System: Data-driven models will be developed for reduced distribution system model while preserving controllable DERs. The models will be integrated into the existing fault detection, isolation, and restoration (FDIR) architecture to improve system outage modeling with enhanced controllable assets.
  • Objective 2 –Controllability and Observability of Distribution System: Using non-linear quasi-static model for distribution systems, voltage- current controllability and observability methods will be developed. The system model will be reduced by mathematical analysis for enhanced observability and controllability of DERs. Metrics will be developed and used to measure the controllability and observability of a distribution system with DERs.
  • Objective 3 – Architecture for DER-based Restoration and Outage Management: The proposed research work will advance the state-of-the-art outage management architecture by:
    1. developing novel feeder restoration algorithms using DERs and Microgrids,
    2. improving feeder response using DER control approach for real-time power balance and voltage regulation in the restored network,
    3. improving outage management and outage modeling using real-time distribution system models and accurate load and DER models, and 4) specifying cyber security requirements for a resilient outage management
