This repository presents a 5 machine model of the Nordic synchronous grid, developed in Matlab Simulink Simscape Electrical. For full details of the model and its design choices, see the document Nordic5_doc.
- Matlab (R2020b)
- Simulink
- Simscape Electrical
Most of the implemented functions use the library file Nordic32_Lib.slx, wind turbine data in the Wind_NREL_data-folder and functions in the Functions-folder. Run open_path_here.m to load all dependencies. Projects are sorted into different folders (see below). For all of these, running main_.m allows the user to recreate results, either from simulation, or from saved examples.
- Main File: main_PSS_controller_design.m
These files are used to desing different load flows and to tune power system stabilizers. Current version is documented in Nordic5_doc.pdf
Contains the simulation examples used in [1].
Main Files:
- main_Ensemble_Nordic5_ideal.m
- main_Ensemble_Nordic5_wind_hydro.m
- main_ensemble_two_hydro_DVPP.m
Contains the simulation examples used in [2]. The implemented wind turbine model is a modified version of the NREL 5 MW baseline wind turbine model [3].
