This paper develops a vectorized semidefinite program (SDP) based on the bus injection model (BIM) and reformulates its dual as an exact-penalty problem, enabling us to develop a scalable three-cut proximal bundle method for feasibility assessment. The proposed bundle method is numerically over 400 times faster than MOSEK with less than 1/2000 of its memory; on the decomposed BIM-SDP, approximately 2 times faster with 75% less memory.","authors_text":"Bohang Fang, Cong Chen, Lijun Ding","cross_cats":["cs.SY","eess.SY"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.OC","submitted_at":"2026-05-25T00:53:16Z","title":"A Scalable Bundle Method for Exact Reformulation of SDP in Three-Phase Power Flow Feasibility"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2605.25319","kind":"arxiv","version":1},"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":"sha256:7c79d5e05e35a6f92b656296b9af2152e35f103e8bda1161797dd227669f63bc","target":"record","created_at":"2026-05-26T02:04:28Z","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":"c9634aae9bc0802e91d275cf9d5553727a79be749af75480bfce6b9cf271e953","cross_cats_sorted":["cs.SY","eess.SY"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.OC","submitted_at":"2026-05-25T00:53:16Z","title_canon_sha256":"59661214cc332372c1a0c4193844322ca2f8405f5a882d99829fbcae9143284a"},"schema_version":"1.0","source":{"id":"2605.25319","kind":"arxiv","version":1}},"canonical_sha256":"cbd635788a9196b3e945fa48f9773c5b4c69648d953668385993e1e169a689c9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"cbd635788a9196b3e945fa48f9773c5b4c69648d953668385993e1e169a689c9","first_computed_at":"2026-05-26T02:04:28.726709Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-26T02:04:28.726709Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Swwtg9U4QkfZZKWm0cSFXUnlaQRZZ38b0QwAC7Go/MzbJnRdrAIxIMQZmBmakRUTyOesDyj/oOSiOEl3tPLaDg==","signature_status":"signed_v1","signed_at":"2026-05-26T02:04:28.727310Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.25319","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7c79d5e05e35a6f92b656296b9af2152e35f103e8bda1161797dd227669f63bc","sha256:a5a5df464a411b944218e92a9b7e3273897f90d2b9d5e9010d4fe9f1f568b24f"],"state_sha256":"01188c07f783d2ef6d07ce2a00c7b7765c8ac94a7e58196289deee4536b82556"}
