We assess the case in which the information is modulated in the deviations of reference voltages of the primary control loops and show that the outputs of the power talk communication channels can be approximated through linear combinations of the respective inputs. We show that the coefficients of the linear combinations, representing equivalent channel gains, depend on the virtual resistances of the primary control loops, i","authors_text":"Cedomir Stefanovic, Marko Angjelichinoski, Petar Popovski","cross_cats":["math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2016-09-26T18:54:38Z","title":"Power Talk for Multibus DC MicroGrids: Creating and Optimizing Communication Channels"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1609.08117","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":"sha256:6a6de15f1bd84e3ab3e88d5dc159b9e75dca8abcc3810dcebb15d6614083c7cf","target":"record","created_at":"2026-05-18T01:03:54Z","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":"81e7444a91a037e5462226a999e96c2cc9f5aa8ae3a59dbbc14ced77a636d912","cross_cats_sorted":["math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2016-09-26T18:54:38Z","title_canon_sha256":"ea7b50260f09a46f72cb87fbed7a3bc15e70428ac69f3513d277b2c697666004"},"schema_version":"1.0","source":{"id":"1609.08117","kind":"arxiv","version":1}},"canonical_sha256":"0cc40dfa4f04eb669ed72507f8978da21a6bfcbabe9135e0cc6321e4d77ebfb1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0cc40dfa4f04eb669ed72507f8978da21a6bfcbabe9135e0cc6321e4d77ebfb1","first_computed_at":"2026-05-18T01:03:54.398615Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:03:54.398615Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"kxUBimHFICvcFTRZ3UPnBilGprZ3lX5elgPqb/JAa4TWVP6F569vNPjulem7lq/v1fFDGdDu/AsR5gs1FeBQAw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:03:54.399154Z","signed_message":"canonical_sha256_bytes"},"source_id":"1609.08117","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6a6de15f1bd84e3ab3e88d5dc159b9e75dca8abcc3810dcebb15d6614083c7cf","sha256:d7ef0e1b9a15db4e98a23374f90da76e070df8320e56b50129dd8d150eab3644"],"state_sha256":"3c308d6fa3551d1532f6d045c9793a6d3a144b7f41095370af4beb481a36f5ba"}
