Resilient restoration of low-inertia networked microgrids with inverter-based energy resource dominationOA
This paper proposes a resilient restoration method for low-inertia networked microgrids(NMGs)dominated with inverter-based energy resources(IBERs).First,a frequency dynamics-aware NMG restoration model is developed,integrating a unified frequency control response framework that accommodates various control strategies while ensuring the system stability during restoration.Case studies for a low-inertia NMG demonstrate the effectiveness of the proposed method.Numerical results show that different IBER control methods could have a significant impact on restoration efficiency and economic losses.Additionally,strict frequency security requirements can predominantly increase the restoration time,calling for a critical trade-off between maintaining network security margins and restoration time for enhancing the resilience of low-inertia NMGs dominated with IBERs.
