Eaton 2015
Keep an efficiency curve per mode (double conversion versus eco/ESS) and the transfer time in the catalogue.
Schneider Electric 2014
Compute eco savings through the PUE stack (UPS loss plus the cooling of that loss), not from the UPS efficiency delta alone.
Uptime Institute Journal 2025
Catalogue AI racks with both 'ratedPowerKw' and 'peakTransientKw' (e.g. 132 vs 150+ for NVL72).
Schneider Electric 2015
In the single-line editor define node types for MV switchgear, MV/LV transformer, LV switchboard/ATS, UPS input/output/distribution boards, STS, PDU, RPP, busway, panelboard and rack PDU, each with rated voltage, rated current, breaking capacity (kAIC/Icu) and withstand rating (SCCR/Icw).
Enerji Piyasası Düzenleme Kurumu (EPDK) 2021
Treat a grid-interactive data-centre battery as storage integrated with a consumption facility: same metering point and a distribution company connection opinion are required.
arXiv (preprint, submitted to IEEE) 2026
Store operating-mode behaviour in the UPS catalogue and electrical model: eco-mode availability, transfer thresholds and timers (for example 0.7 p.u./20 ms to battery), and a post-event rectifier ramp time.
U.S. Environmental Protection Agency (ENERGY STAR) 2017
Store efficiency at 25/50/75/100% load for each normal mode (double-conversion, eco/ESS) in UPS catalogue entries, measured to IEC 62040-3.
ACM e-Energy '26 (author version on arXiv) 2025
Add a ride-through check to the electrical module: compare the selected UPS input tolerance (IEC 62040-3 class) and IT tolerance (ITI/CBEMA) against the applicable grid-code LVRT envelope for the site's region, and flag the gap.
Batteries (MDPI AG) 2025
In LFP module design, evaluate inter-cell thermal resistance (interface insulation) together with measures that cut heat release to stop propagation; in the model an interface resistance of hR = 100 W·m^-2·K^-1 alone suppressed it.
Batteries (MDPI AG) 2026
For confined battery packs and cabinets, evaluate a fast flame-knockdown agent (such as heptafluoropropane) together with an agent or approach giving long-lasting cooling (such as perfluorohexanone); no single agent stopped heat transfer to neighbouring cells.
Schneider Electric 2018
Battery catalog: chemistry (VRLA, LFP, NMC, LMO, NCA, LTO, LCO), specific energy, design and cycle life, rated temperature, footprint and weight per kWh, recharge time and compatible UPS models.
IEEE Access (Institute of Electrical and Electronics Engineers (IEEE)) 2025
For a UPS that will provide grid services, define the SOC window (for example 20-80%) and show by calculation that backup autonomy is preserved inside it.
Consulting-Specifying Engineer 2025
Make pre-action (single or double interlock) with aspirating detection the default white-space suppression option; keep clean agent and water mist selectable.
arXiv (Aalborg University) 2026
For large sites, capture grid-code inputs per jurisdiction (FRT curve, MW/min ramp limit, power-quality limits) as project inputs and flag UPS settings that transfer to battery or generator on shallow sags.
IET Generation, Transmission & Distribution (Institution of Engineering and Technology (IET)) 2026
For large or AI facilities, record the UPS's fault ride-through behaviour (momentary cessation versus ride-through with minimum grid draw), the inverter current limit and the post-fault ramp rate, alongside the point-of-interconnection short-circuit ratio.
Energy Advances (Royal Society of Chemistry (RSC)) 2025
For UPS duty with a few cycles a year and minutes of autonomy, compare battery chemistries by environmental impact categories (GWP, ecotoxicity, resource depletion) as well as energy density, because production and EOL dominate.
IEEE Access (Institute of Electrical and Electronics Engineers (IEEE)) 2026
Require block-level (per-unit) voltage and resistance monitoring in UPS battery monitoring rather than string totals, citing that one weak unit in a series string limits the whole string's capacity.
arXiv preprint (University of Michigan) 2026
Layer storage by timescale (chip/server sub-ms to ms, rack ms to seconds, UPS and GiUPS sub-second to 10 s, BESS minutes to hours) and show each layer's duty in the coordination scheme.
Advances in Applied Energy (Elsevier BV) 2026
Layer storage by timescale: GPU/server supercapacitors for sub-second swings, rack BBUs for minutes, facility GiUPS and BESS for grid services and longer durations; show each layer's duty and coordination separately in the architecture.
Eaton 2021
When sizing UPS batteries, model a grid-services band on top of the required autonomy.
U.S. Department of Energy / U.S. EPA (ENERGY STAR) 2013
When ingesting vendor UPS efficiency figures, record the input configuration (three-phase) and whether the values follow ENERGY STAR or IEC 62040-3 methods.
Vertiv 2023
Model UPS battery state of charge as partitioned: reserved backup energy used for autonomy checks plus an optional grid-service band.
Huawei Digital Power 2025
Import RD 01-21 as parametric AI-hall templates (rack kW, racks per module, module kW, redundancy of fan walls/TMUs/towers, generator and transformer counts) and as golden test cases for capacity math.
Schneider Electric 2020
Add a processCoupling flag (in_series, in_parallel) to edge sites; for in_series default the availability target to Tier III equivalent and require redundant UPS/cooling (N+1 or 2N) plus maintenance bypass.
