It will be highly appreciated if anyone can send the file to tosikurrahman@gmail.com thanks in advance

This 5-bus example comes with SimPowerSystems.

You can load the model by typing the following in MATLAB.

>> power_LFnetwork_5bus

MATLAB: Rename BUS

Hi,

if you create a sample BUS with the bus editor you can export the BUS in the Model Explorer (Ctrl + H) of your Simulink Model (Base Workspace). It will generate an .m-file where you can set the bus names and run on model startup:

% -------------------------------------------------------------------

%  MATLAB file generated by Simulink.saveVars 
% -------------------------------------------------------------------
FA = Simulink.Bus;
FA.Description = '';
FA.DataScope = 'Auto';
FA.HeaderFile = '';
saveVarsTmp{1} = Simulink.BusElement;
saveVarsTmp{1}.Name = 'cog';
saveVarsTmp{1}.DataType = 'double';
saveVarsTmp{1}.Complexity = 'real';
saveVarsTmp{1}.Dimensions = 1;
saveVarsTmp{1}.DimensionsMode = 'Fixed';
saveVarsTmp{1}.SamplingMode = 'Sample based';
saveVarsTmp{1}.SampleTime = -1;
saveVarsTmp{1}(2, 1) = Simulink.BusElement;
saveVarsTmp{1}(2, 1).Name = 'mass';
saveVarsTmp{1}(2, 1).DataType = 'double';
saveVarsTmp{1}(2, 1).Complexity = 'real';
saveVarsTmp{1}(2, 1).Dimensions = 1;
saveVarsTmp{1}(2, 1).DimensionsMode = 'Fixed';
saveVarsTmp{1}(2, 1).SamplingMode = 'Sample based';
saveVarsTmp{1}(2, 1).SampleTime = -1;
FA.Elements = saveVarsTmp{1};
clear saveVarsTmp;

MATLAB: Solving sytem of ODE’s

The only problem I see is that ‘P1’ should be divided by ‘M1’ ...

f = @(t,z) [z(2); z(2)*(-D1/M1)+P1/M1-(a12/M1)*sin(z(1)-z(3)); z(4); (-D2/M2)*z(4)+(P2/M2)-((a21/M2)*sin(z(3)-z(1)))];

Unless I’m misinterpreting your code.
