Dev:

PowerModels.jl is a Julia/JuMP package for Steady-State Power Network Optimization. It is designed to enable 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 the power network formulations (e.g. AC, DC-approximation, SOC-relaxation, ...). This enables the definition of a wide variety of power network formulations and their comparison on common problem specifications.

Core Problem Specifications

• Power Flow (pf)
• Optimal Power Flow (opf)
• Optimal Transmission Switching (ots)
• Transmission Network Expansion Planning (tnep)

Core Network Formulations

• AC (polar and rectangular coordinates)
• DC Approximation (polar coordinates)
• LPAC Approximation (polar coordinates)
• SDP Relaxation (W-space)
• SOC Relaxation (W-space)
• QC Relaxation (W+L-space)
• IV (rectangular coordinates)

Network Data Formats

• Matpower ".m" files
• PTI ".raw" files (PSS(R)E v33 specfication)

The package documentation includes a variety of useful information including a quick-start guide, network model specification, and baseline results.

Additionally, these presentations provide a brief introduction to various aspects of PowerModels,
