JuliaGrid

JuliaGrid is an open-source, easy-to-use simulation tool/solver for researchers and educators provided as a Julia package, with source code released under MIT License. JuliaGrid is inspired by the Matpower, an open-source steady-state power system solver, and allows a variety of display and manipulation options.

The software package, among other things, includes:

  • AC power flow analysis,
  • DC power flow analysis,
  • non-linear state estimation (work in progress),
  • linear DC state estimation (work in progress),
  • linear state estimation with PMUs only (work in progress),
  • least absolute value state estimation (work in progress),
  • optimal PMU placement,
  • bad data processing (work in progress).

Main Features

Features supported by JuliaGrid can be categorised into three main groups:

  • Power Flow - performs the AC and DC power flow analysis using the executive function runpf(...);

  • State Estimation - performs non-linear, DC and PMU state estimation using the executive function runse(...), where measurement variances and sets can be changed (work in progress);

  • Standalone Measurement Generator - generates a set of measurements according to the AC power flow analysis or predefined user data using the executive function runmg(...).

Installation

JuliaGrid requires Julia 1.2 and higher. To install JuliaGrid package, run the following command:

pkg> add https://github.com/mcosovic/JuliaGrid

To load the package, use the command:

julia> using JuliaGrid

Quick Start Power Flow

julia> results = runpf("dc", "case14.h5", "main", "flow")
julia> results = runpf("nr", "case14.xlsx", "main"; max = 20, stop = 1.0e-8)

Quick Start Measurement Generator

julia> results = rungen("case14.h5"; pmuset = "optimal", pmuvariance = ["all" 1e-5])
julia> results = rungen("case14.h5"; legacyset = ["redundancy" 3.1], legacyvariance = ["all" 1e-4])
