Search run: 2026-08-14 seed batch

Page status: generated search-run record.

Protocol: 0.1.0 Run date: 2026-08-14 Purpose: small seed expansion for the scoping-review matrix; not an exhaustive database search and not double-coded.

Queries

1. power system network reduction Kron Ward equivalent multiconductor paper
2. power system parallel line redundant flow limits optimization paper
3. CIM CGMES TopologicalNode connectivity topology processing official documentation

The web search run returned the following primary or official records used for seed coding:

• Structure- & Physics-Preserving Reductions of Power Grid Models
• Structure-preserving Optimal Kron-based Reduction of Radial Distribution Networks
• CGM Building Process Implementation Guide v2.0
• Identifying Redundant Flow Limits on Parallel Lines

Matrix effects

The run added EV-0002 through EV-0004 to review/evidence-matrix.csv; EV-0001 was already present. All four rows are single_coded and pass scripts/check_evidence_matrix.py. The records are deliberately coded with scoped exactness and limitations rather than being promoted to established claims.

Limitations

• No IEEE Xplore, Scopus, Web of Science, Compendex, or MathSciNet export was available in this run.
• Deduplication, citation chasing, full-text screening, and second-coder review remain outstanding.
• Search-result snippets were used only to locate primary/official records; the matrix notes identify where full-text coding is still incomplete.
