PowerModels.jl: An Open-Source Framework for Exploring Power Flow Formulations

zzjcy

一个新的PF和OPF开源软件，比较难得的是支持的建模方式比较多，包括AC（直角坐标、极坐标）、DC（极坐标）、SOCP和QC

, y5 `6 m0 {: h0 o1 h) p) nPowerModels.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.
