Making Our Power Grid Sweat
summary
A transformer thermal model based on the IEC loading guide simulates hotspot temperature and top-oil profiles from measured load, transformer spec sheets and ambient weather to estimate aging and permissible load increases; validated against field measurements and open sourced on GitHub, it currently models oil-filled power and distribution transformers with passive/forced cooling and predicts about 600 MVA potential of additional load across the grid (roughly 100k–200k households) by safely scaling static limits or defining cyclic ratings.
