This panel session provides a high-level overview of Duke Energy’s practice of evaluating the impacts of inverter-based microgrid (battery storage and PV facilities to island portion of distribution feeder). Topics will include engineering aspects such as power flow, protection, stability, and power quality. Session will elaborate on data needs, analysis tools, and evaluation criteria. The session also covers project management aspects such as when these studies should be performed under the governing state interconnection procedures.

Key Takeaways

• Engineering and project management lessons learned
• Challenges experienced from some of Duke Energy's installations
• Where to begin the process of incorporating inverter-based microgrids to the distribution system for islanding purposes
• Key project management level considerations when creating the system impact study
