The review addresses two key aspects, inertia estimation methods and control strategies for emulating inertia via power converters, emphasizing the role of the interlinking converter (ILC) as a bidirectional interface for inertia support between the AC and DC subsystems. . Strategy I: All battery inverters work in GFM mode with power sharing by droop control (50% GFM inverters). Based on the study, select the more appropriate control strategy for the microgrid. DGs, which include Renewable Energy Sources (RESs), Energy Storage Systems (ESSs), and new load types such as. . This report is available at no cost from the National Renewable Energy Laboratory (NREL) at www. This research reviews the low-inertia problem in the microgrid with a significant share of renewable energy, reviews virtual inertia emulation, and introduces the basics of designing and regulating virtual. .
