resilience power system in matlab

One way to simulate and analyze the resilience of a power system in MATLAB is by using the Power System Toolbox. This toolbox provides functions for building power system models, simulating the operation of power systems, and performing dynamic analysis.

To start, you can use the power_system function to create an empty power system model:

main.m
sys = power_system('create');
30 chars
2 lines

Then, you can add components to the model using the various add functions provided by the toolbox. For example, to add a generator to the model, you can use the addGenerator function:

main.m
gen = addGenerator(sys, 'Name', 'G1', 'ActivePower', 100e6, 'Voltage', 20e3);
78 chars
2 lines

You can also add other components such as loads, transformers, and transmission lines.

Once you have built your power system model, you can simulate its operation using the sim function. For example, to simulate the operation of the model for 10 seconds, you can use the following code:

main.m
tspan = [0 10];
options = simset('SrcWorkspace', 'current');
sim(sys, tspan, options);
87 chars
4 lines

During the simulation, you can use the various visualization functions provided by the toolbox to monitor the behavior of the system, such as plot functions to plot voltage and current waveforms.

To analyze the resilience of the system, you can simulate various scenarios such as component failure or load shedding and observe how the system responds. For example, you can simulate the loss of a transmission line using the set_param function:

main.m
set_param('model/Line1', 'R', '1e10', 'X', '1e10');
52 chars
2 lines

This code sets the resistance and reactance of Line1 to very large values, effectively removing it from the system. You can then continue the simulation and observe how the system responds to the loss of the transmission line.

Overall, the Power System Toolbox provides a wide range of functions and tools for analyzing the resilience of power systems in MATLAB.
