We assume wind is strong enough to let each WTs to produce the required power and propose different closed-loop Model Predictive Control (MPC) dispatching algorithms. Similarly to existing approaches based on MPC, our methods do not require changes in WT hardware but only software changes in the SCADA system of the WF. However, differently from previous MPC schemes, we augment the model of a WT with an ARMA predictor of the wind turbulence, which r","authors_text":"Fabio Sarzo, Giancarlo Ferrari-Trecate, Simone Mancini, Stefano Riverso","cross_cats":["math.OC"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SY","submitted_at":"2015-03-22T18:35:18Z","title":"Model predictive controllers for reduction of mechanical fatigue in wind farms"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1503.06456","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":"sha256:0b70d4ac1eec6a958ae7d77939a2e15e96c3f35f1cefd1ab2e8d916a0ab58924","target":"record","created_at":"2026-05-18T02:20:38Z","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":"adff2c175ade5d112a62a8b1764a0eec4e65aff9d552ffde86ae6313152ec56c","cross_cats_sorted":["math.OC"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SY","submitted_at":"2015-03-22T18:35:18Z","title_canon_sha256":"d4486f64f213919281903a1aca7e74618c8a2dfa4b56a6dc13affb82805212e5"},"schema_version":"1.0","source":{"id":"1503.06456","kind":"arxiv","version":1}},"canonical_sha256":"cf78f39e880168e0c676cd76bfce4ebb6cd67dae2e10b5b6e3d0ac587161d4b0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"cf78f39e880168e0c676cd76bfce4ebb6cd67dae2e10b5b6e3d0ac587161d4b0","first_computed_at":"2026-05-18T02:20:38.347870Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:20:38.347870Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"/7fRQ2c2+uy6yBB+921lAEkIncddjOthrslOjZVBKNBuDA29Xiw74cavtnYB7E6OPhxt78p3zgKJRRg+VFBMCg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:20:38.348649Z","signed_message":"canonical_sha256_bytes"},"source_id":"1503.06456","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0b70d4ac1eec6a958ae7d77939a2e15e96c3f35f1cefd1ab2e8d916a0ab58924","sha256:01b52ed5a900fd016d46e5391c8975a96924ea725bb547cee416b19b2de7996f"],"state_sha256":"380f0a053ee0cc2bf927112f773ca65e977450ebfa066af027cb62b5a7235d46"}
