08 Oct 2010 Newton-Raphson Loadflow These matlab m files are used to calculate bus voltages and angles using Newton Raphson iterative me Author: PRAVI

@Omar: I guess, this is error is bcs of the different versions of matlab. Keep the line 60 (loadflow.m) commented.

%Sij = sparse(Sij);

And try again.

09 Apr 2014 Newton-Raphson Loadflow These matlab m files are used to calculate bus voltages and angles using Newton Raphson iterative me Author: PRAVI Sarde, Hanumant

hello sir after executing the program the command shows the following error

1 2Error using fprintf
Function is not defined for sparse inputs.

Error in loadflow (line 95)
fprintf('%4g', p); fprintf('%4g', q); fprintf(' %8.3f', Pij(p,q)); fprintf(' %8.3f',
Qij(p,q));

Error in nrlfppg (line 160)
loadflow(nbus,V,del,BMva); % Calling Loadflow.m..

can u please make me understand why the error occured
