However, conventional ACOPF formulations rely on steady-state models and neglect generator dynamics, which can result in operating points that are economically optimal but dynamically unstable. This paper proposes a novel, data-driven approach to incorporate generator dynamics into the ACOPF using Gaussian Process (GP) models. Specifically, it introduces an exponential surrogate funct","authors_text":"Deepjyoti Deka, Ferdinando Fioretto, Kaarthik Sundar, Vincenzo Di Vito","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.OC","submitted_at":"2025-07-30T20:51:58Z","title":"Stability-Constrained AC Optimal Power Flow--A Gaussian Process-Based Approach"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2507.23094","kind":"arxiv","version":3},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:21527f41286c7c0084cc3ebfa9c893e0f7528c3ac28f02ed8aba226dcd425899","target":"record","created_at":"2026-05-17T23:39:01Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"7e5d71d46318dafd97f0919c5cd263d83d562e27f0636db585e1ff7aeb3a989a","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.OC","submitted_at":"2025-07-30T20:51:58Z","title_canon_sha256":"aec19f0b7d3e7ee5dd66c1a4af80367ace414504baa7809614dd8fe07034e51b"},"schema_version":"1.0","source":{"id":"2507.23094","kind":"arxiv","version":3}},"canonical_sha256":"eef90e9b835b2224bef4a23788f59d54ab0af1c32c02321131c1b6bcf7300f2a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"eef90e9b835b2224bef4a23788f59d54ab0af1c32c02321131c1b6bcf7300f2a","first_computed_at":"2026-05-17T23:39:01.166877Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:39:01.166877Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"PY6KPFgcjQkqcxQ6Spe3Sr7GXbc+VGhLQQ4z7XUDK1yDQWrYWaAXC5V2vfn+N1OIE+lbUuL9Po0U++WsMj9XDQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:39:01.167596Z","signed_message":"canonical_sha256_bytes"},"source_id":"2507.23094","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:21527f41286c7c0084cc3ebfa9c893e0f7528c3ac28f02ed8aba226dcd425899","sha256:fbce1757a45405f7bfb32413e5f539dafd3df1a629b4e876a914d631abb27d7b"],"state_sha256":"b72f87bb413870889eb77a5ce484276f8c4c124e7b7124a8fc93e4e89927875e"}
