HarmonicPowerFlow.jl

An open source module to solve the harmonic power flow problem in Julia. Nonlinear devices are represented by their Norton equivalents using either a coupled or uncoupled approach. A system of nonlinear equations is assembled and solved using the Newton-Raphson algorithm.

This package was created as part of a master's thesis at TU Berlin, in collaboration with DAI-Labor and elena international.

Comments, questions and contributions are highly welcome.

Usage

Install the module via the package manager:

]add HarmonicPowerFlow

or

using Pkg; Pkg.add("HarmonicPowerFlow")

To run a harmonic power flow, the following objects are required:

• a PowerGrid struct, containing information on buses and lines which can either be imported or created manually,
• a Settings struct with simulation parameters and
• the Norton equivalent parameters of the nonlinear devices connected to the grid.

An example of a simple harmonic power flow can be found here.
