PowerModelsITD.jl is an extention package based on PowerModels.jl and PowerModelsDistribution.jl for steady-state Integrated Transmission-Distribution (ITD) power network optimization. It is designed to enable the computational evaluation of emerging power network formulations and algorithms in a common platform. The code is engineered to decouple problem specifications (e.g. Power Flow, Optimal Power Flow, ...) from power network formulations (e.g. AC polar, AC rectangular, linear-approximation, SOC-relaxation, ...) on both transmission and distribution system(s). Thus, enabling the definition of a wide variety of ITD power network formulations and their comparison on common problem specifications.
- Integrated T&D Power Flow (pfitd)
- Integrated T&D Optimal Power Flow (opfitd)
- Integrated T&D Optimal Power Flow with storage costs (opfitd_storage)
- Integrated T&D Optimal Power Flow with on-load tap-changer (opfitd_oltc)
- Integrated T&D Optimal power flow at transmission and minimum load delta at distribution system (opfitd_dmld)
Note: left is the formulation used to model the transmission system - right is the unbalanced formulation used to model the distribution system(s).
