Which assets, which datasets, which models — and why each exists
What we are building
A Pakistan smart-grid digital twin: one yard of linked objects driven by PRECON + IEEE 13-Bus + DGA/LSTM models — so you can see load, oil health, NILM, and outages in one place.
Close research gaps between residential datasets (PRECON/NILM), standard feeders (IEEE 13), transformer oil chemistry (DGA), and predictive models (LSTM) on a live 3D twin.
Objects we are working on
Distribution Transformer
TX-GUL-03Primary digital twin asset (Gulberg III, Lahore)
Why · Thermal + electrical health of the feeder transformer is the core twin we predict and mitigate.
Smart Meter Cluster
SM-PRECONHousehold aggregate + appliance NILM channels
Why · Shows which loads (AC, UPS, pump, kitchen) drive peak demand on the transformer.
UPS / Battery Island
UPS-ISLANDPakistan outage realism (LESCO-style shed)
Why · When feeder voltage/freq drops, UPS islands keep critical loads — twin must track that mode.
IEEE 13-Bus Feeder Stub
FD-IEEE13Standard 4.16 kV test feeder mapped to Pakistan load
Why · Gives a research-grade power-flow topology (buses, pu, unbalance) instead of a fake single node.
4 PRECON Residential Houses
HOUSE-PRECONH-LHR-07 Gulberg · H-LHR-12 DHA · H-LHR-21 Johar · H-LHR-33 Model Town
Why · All Lahore PRECON homes feed meters → transformer; UPS homes also island on outage.
Oil DGA Sample Port
DGA-PORTDissolved gas sampling on transformer oil
Why · Early fault chemistry (H₂, C₂H₂, C₂H₄…) before thermal runaway shows on the tank.
Backup Generator Pad
GEN-BACKUPSite backup during prolonged outage
Why · Pakistan sites often run gensets under shed — twin tracks when backup supports load.
Wires / links — what each connection does
PRECON houses → Smart meters
Carries · Appliance kW (AC, UPS, pump…)
Why · NILM needs per-home channels from LUMS PRECON.
dataSmart meters → TX-GUL-03 LV
Carries · Aggregated residential load
Why · Feeder demand that heats the transformer twin.
powerHouses with UPS → UPS island
Carries · Critical load during shed
Why · Pakistan outage realism — PRECON UPS channels.
backupIEEE 13 feeder → TX-GUL-03 HV
Carries · 4.16 kV bus voltage / pu
Why · Standard power-flow topology for research.
powerDGA port → Transformer oil
Carries · Gas ppm → Duval code
Why · Chemistry early-warning before thermal runaway.
chemistryBackup genset → TX / LV bus
Carries · Emergency kW on outage
Why · PK restore path when feeder is down.
backupMeter aggregate → LSTM forecast
Carries · Load time series
Why · Train/eval MAE·RMSE·R² on PRECON-shaped demand.
dataDatasets — what & why
LUMS PRECON
LUMS — Pakistan Residential Energy Consumption (appliance channels)
Why · Real Lahore-style residential demand shapes and NILM labels (AC, UPS, pump, iron…).
IEEE 13-Node Test Feeder
IEEE PES / OpenDSS reference feeder (4.16 kV)
Why · Industry-standard topology for voltage pu, phase unbalance, and bus stress.
Transformer DGA chemistry
Dissolved gas analysis (IEC / Duval-style codes)
Why · Oil gases diagnose PD, discharge, and thermal faults inside the tank.
Pakistan grid events
Simulated LESCO-style outage / UPS / load-shed timeline
Why · Makes the twin behave like a Pakistani feeder, not a US lab bench only.
Models — what & why
Oil thermal RC model
Physics
Why · Maps loading % → oil temperature rise for the transformer tank twin.
LSTM load forecast
Deep learning (sim eval)
Why · Predicts next load window; MAE / RMSE / R² / F1 score the research gap.
NILM disaggregation
Signal / appliance split
Why · Splits meter kW into appliance channels so operators see what is driving peaks.
Duval / DGA fault codes
Chemistry classifier
Why · Turns gas ppm into Normal / PD / D1–D2 / T1–T3 for early intervention.
Cyber-physical sync metrics
Fidelity / lag
Why · Measures how close the digital twin stays to the ‘physical’ MQTT stream.
