The Energynet simulation has been shown to be a statistically valid predictor of actual network conditions indicated by field sensor measurements.
14 Fish Substation circuit voltage profiles - field vs. simulation
Conditions of the Validation Tests
Large regional power delivery system incorporating nearly 250 distribution circuits.
Varying operating conditions.
Field data from 864 widely-dispersed monitoring points, the majority out on distribution radials away from substations.
Uniform field monitoring density - real and reactive power flow and line voltage profile for every circuit.
Individual distribution loads extrapolated from substation data or infilled using Energynet software.
Findings
Simulation and field power flow values are very strongly correlated.
Simulation and field voltage values are not statistically different.
2% variability between simulation and field voltage values - well within a ±5% range of interest.
Simulation can reflect actual circuit voltage profile as well as voltage level.
