The paper introduces an analytical approach to predict the no-load flux density spatial repartition of inner permanent magnet tubular-linear synchronous machines (IPM T-LSMs). It considers a trapezoidal waveform whose maximum value is predicted using a simple magnetic equivalent circuit of an elementary part of the machine. Then, the accuracy of the proposed approach is enhanced by the incorporation of a mover permeance function that accounts for the PM luxconcentrating arrangement.

A Traffic Light Controller PETRI_NET (Finite State Machine) Implementation.

 

An implementation of FSM approach can be followed in systems whose tasks constitute a well-structured list so all states can be easily enumerated. A Traffic light controller represents a relatively complex control function

The purpose of distribution network reconfiguration (DNR) is to determine the optimal topology of an electricity distribution network, which is an efficient measure to reduce network power losses. Electricity load demand and photovoltaic (PV) output are uncertain and vary with time of day, and will affect the optimal network topology. Single-hour deterministic DNR is incapable of handling this uncertainty and variability. Therefore, this paper proposes to solve a multi-hour stochastic DNR (SDNR).

The dataset contains internal faults in power transformer and phase angle regulators (PAR) in a 5-bus interconnected system. It also has 6 other power system transients which include magnetising inrush, sympathetic inrush, external faults with CT saturation, capacitor switching, non-linear load switching, and ferroresonance. There are 88128 internal fault files and 12780 files of other transient disturbances. The faults and transients are simulated in PSCAD/EMTDC and the output files are in text format.

Instructions: 

Detailed description of all data files is provided in the *Dataset_Readme.pdf* file along with the dataset.

Grid planning benchmark dataset and scripts for the paper "A Hybrid Optimization Method Combining Network Expansion Planning and Switching State Optimization".

Instructions: 

Instructions

  1. Clone the repository
  2. Install pandapower and PowerModels.jl (see 'Installation Instructions')
  3. Run the optimization, e.g., with python run_greedy.py

 

This repository contains these subfolders with the following data:

  • "power_system_data" containing the power system benchmark cases included additional line and replacement measures
  • "scaled_loadcases" contains the data to reproduce the mathematical programming results

 

Main script to run the hybrid optimization method

The script "run_greedy.py" runs the greedy heuristic combined with the PowerModels.jl optimization framework. An example call starting a combined optimization of switching measures and line measures for the 'brigande' test case is:

python run_greedy.py -grid 'brigande' -kind 'combo' -max_iterations 3 -res_dir './results'

See more options with:

python run_greedy.py -h

If you have trouble using the PowerModels.jl interface, you can just run the script without PowerModels.jl. This gives you a greedy optimization of switching and line measures. Try:

python run_greedy.py -pm ''

 

Additional script to run the PowerModels.jl Optimization

The repository also contains a script "run_powermodels.py" which runs the PowerModels.jl based results with the pandapower-python to PowerModels.jl-julia interface

The script has several command line options:

  • model (str) - The PowerModels.jl power model e.g. "DCPPowerModel"
  • solver (str) - The solver to use, e.g. "juniper", "gurobi"
  • grid (str) - optional if you only want to calculate one grid, e.g. "brigande"
  • kind (str) - the optimizations to run, e.g. "tnep,ots,repl". Can only be a part of these like "tnep,repl"

Example to run the model "DCPPowerModel" with "gurobi" as a solver for the grid "brigande" with the time series loadcases "ts" for the REPl "repl" problem:

python-jl run_powermodels.py --model="DCPPowerModel" --solver="gurobi" --grid="brigande" --kind="repl"

 

Installation instructions

You need the following software to run the script:

The python-julia interface might require some additional installations. See the following link for details: https://pandapower.readthedocs.io/en/latest/opf/powermodels.html
