Hi Dexter,

To perform an N-1 contingency test in MATPOWER, you can follow these steps:

1. First, use the 'loadcase' function to load the data of the required case file into MATLAB.
2. Next, access the 'branch' field of the case data to determine the number of contingencies. You can remove the desired contingency by modifying the data accordingly.
3. Finally, use the 'rundcpf' function to run the power flow analysis for each contingency case.

For more detailed information on how to use MATPOWER and these specific functions, I recommend referring to the official documentation. You can find the MATPOWER manual at this link: https://matpower.org/docs/MATPOWER-manual.pdf

Here is an example code snippet that demonstrates the process:

% Load the base case data 
mpc = loadcase('case5'); 

% Identify the contingencies 
n_contingencies = size(mpc.branch, 1); 
results = cell(n_contingencies, 1); 

% Run power flow for each contingency 
for i = 1:n_contingencies 
    % Create a copy of the base case 
    contingency_case = mpc; 
    
    % Remove the i-th contingency 
    contingency_case.branch(i, :) = []; 
    
    % Run power flow for the contingency case 
    results{i} = rundcpf(contingency_case); 
end 

Hope this helps!
