Data center interconnection workflow in Electrisim
Electrisim supports a practical data-center interconnection path on existing engines: site screening with headroom and contingencies, ANSI pre/post short circuit, and ANDES RMS dynamics with an optional computational-load ride-through check. It does not bundle MMWG/WECC/ISO cases, read PSS/E CMLD/PERC1 .dyr records, or run EMT (ParaEMT/dpsim).
Where to start: New diagram → Data center interconnection (utility pocket) tutorial, or public IEEE 118/300 transmission benchmarks for larger networks. PSS/E .raw and TARA .con are not imported directly. Reference: Data center workflow in documentation.
Site screening (Beta)
Simulate → Data Center Site Screening (Beta). Tick candidate loads, set MW sizes and power factor, voltage and thermal limits, and optional capped N-1-1. Results show headroom MW, worst N-1 and N-1-1 cases, and an upgrade likely flag when limits are exceeded.
Short circuit (pre vs post)
On Simulate → Short Circuit, Pandapower tab: tick ANSI/IEEE C37 (beta) and Compare pre/post project. List project elements removed in the pre case (data-center load, on-site gen, BESS). Export pre/post CSV; for single-line-to-ground faults, use I½ sym at the POI for NGR sizing.
Dynamics and computational load
Simulate → Transient Stability (ANDES) with optional bus fault, line outage, generator trip, and POI metrics. On the Load dialog, Data center tab enables a ride-through CSV (time vs minimum voltage pu). After TDS, Electrisim compares POI RMS voltage to that curve (pass/fail). This models IT constant-P and cooling via ZIP fields — not CMLD/PERC1 and not sub-cycle EMT.
Out of scope in this release: Copyrighted WECC/MMWG/ERCOT/ISO base cases, CMLD/PERC1 dynamic load records, transformer inrush, and sub-cycle sag (EMT) require external tools or future integration.
