Asset Thermal Models: Expanding the Family of Thermal Models To C...
summary
All primary asset types now get temperature estimates so operators can push capacity safely: a Cable Thermal Model (finite-difference 1D heat equation, soil resistivity input) and a Switchgear Thermal Model (Newton cooling) join the existing transformer model. Validation shows transformer and cable outputs within a few degrees and transformer accuracy around 5°C; one summer day at 34°C and 120% load yields an estimated 7 days of aging in one day. Models are open source on GitHub and PyPI.
