Hello,
I am comparing different techniques (Current Injection (Already calculated), Newton Raphson (Already Done), and Backward-Forward Sweep (facing problem)) for load flow analysis for three phase unbalanced system though Matlab.
From couple of weeks, I have tried to develop matlab code for Backward-Forward sweep but failed. It will be great help if I get code (even general/conventional method will be very helpful for me) for backward-forward sweep for three-phase (not single phase).
Looking forward for your help. Thanx.
Cheers,
Muhammad
Did you try to check Mathcentral https://www.mathworks.com/matlabcentral/fileexchange/?s_tid=gn_mlc_fx, there is a possibility someone put there a simple code to do that.

//Example No. 3.2
clc;
clear;
close;
format('v',8);
//Given Data :
n=0.1;//teeth ratio
ETAg=90/100;//efficiency
J0=0.4;//Kg-m^2
J1=10;//Kg-m^2
TL=50;//N-m
N=1400;//speed in rpm
//Solution :
J=J0+n^2*J1;//Kg-m^2
T=n*TL/ETAg;//N-m
MotorSpeed=2*%pi*N/60;//rad/sec
Pdev=MotorSpeed*T;//Watt
disp(J,"Equivalent Inertia in Kg-m^2 : ");
disp(T,"Load Torque refered to motor side in N-m : ");
disp(Pdev,"Power developed by motor in watt : ");
You can also spend time to find the relevant code here, but you also need to share some of your codes: http://getreport.in/idea/hackchina-matlab-code
