The work addresses these issues from two different perspectives. At the device level, it presents a novel control design for grid-forming resources using an adaptive internal model principle. This scheme utilizes real-time frequency estimates to ensure zero steady-state tracking error, maintaining stable inverter operation even during abrupt frequency deviations caused by the tripping and reconnection of large-scale data centers. At the network level, it enhances real-time congestion management through network topology optimization. By utilizing a linear AC power flow model rather than the standard DC approximation, the research provides a more accurate framework for transmission switching decisions in real-time operations timescales. Preliminary results from a network topology optimization application (wildfire risk minimization) suggest that this model can lead to more realistic switching decisions, considering the actual network physics more accurately.\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Mitigation of Data Center-Induced Congestion and Resilient Frequency Control of Inverters in Power Grids"}],"uid":"28475","created_gmt":"2025-12-29 20:58:16","changed_gmt":"2026-01-05 14:33:25","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-01-12T11:00:00-05:00","event_time_end":"2026-01-12T13:00:00-05:00","event_time_end_last":"2026-01-12T13:00:00-05:00","gmt_time_start":"2026-01-12 16:00:00","gmt_time_end":"2026-01-12 18:00:00","gmt_time_end_last":"2026-01-12 18:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Room C1215, CODA","extras":[],"related_links":[{"url":"https:\/\/gatech.zoom.us\/j\/99529652234","title":"Zoom link"}],"groups":[{"id":"434371","name":"ECE Ph.D. Proposal Oral Exams"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"},{"id":"1808","name":"graduate students"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
