i am working on IEEE 33 bus system and i have static load data so that i want use dynamic data like hourly load consumption data to get current values and losses for proposed test system,hence i request please guide me to writing the code in matlab

Dear sameer mohammad,
For a start, try running the attached file "UntitledElpa". It plots the load variations as are given in:
clc;
clear all;
format long
Industrial = [6:1:18];
Residential = [2,3,4,5,19,20,21,22,23,24,25];
Commercial = [26,27,28,29,30,31,32,33];
mpc = case33Loss202;
mpc.bus(2,3)
LoadVariInd = [0.56;0.54;0.52;0.50;0.55;0.58;0.68;0.80;0.90;0.98;1.00;0.94;0.95;0.96;0.90;0.83;0.78;0.72;0.71;0.70;0.69;0.67;0.65;0.60];
LoadVariRes = [0.69;0.65;0.62;0.56;0.58;0.61;0.64;0.76;0.9;0.95;0.98;1;0.99;0.99;1;0.96;0.96;0.94;0.93;0.92;0.91;0.88;0.84;0.72];
LoadVariCom = [0.2;0.19;0.18;0.18;0.2;0.22;0.25;0.4;0.65;0.86;0.9;0.92;0.89;0.92;0.94;0.96;1;0.88;0.76;0.73;0.65;0.5;0.28;0.22];
for i=1:length(Industrial(1,:))
AA(i,:)=(mpc.bus(Industrial(1,i),3))*1e3;
BB(i,:)=(mpc.bus(Industrial(1,i),4))*1e3;
end
for i=1:length(Residential(1,:))
AA1(i,:)=(mpc.bus(Residential(1,i),3))*1e3;
BB1(i,:)=(mpc.bus(Residential(1,i),4))*1e3;
end
for i=1:length(Commercial(1,:))
AA2(i,:)=(mpc.bus(Commercial(1,i),3))*1e3;
BB2(i,:)=(mpc.bus(Commercial(1,i),4))*1e3;
end
P = sum(AA);
Q = sum(BB);
S = (P^2+Q^2)^0.5;
P1 = sum(AA1);
Q1 = sum(BB1);
S1 = (P1^2+Q1^2)^0.5;
P2 = sum(AA2);
Q2 = sum(BB2);
S2 = (P2^2+Q2^2)^0.5;
for j=1:length(LoadVariInd(:,1))
Demand(j,:)=LoadVariInd(j,:)*S;
Demand1(j,:)=LoadVariRes(j,:)*S1;
Demand2(j,:)=LoadVariCom(j,:)*S2;
end
E=max(Demand);
E1=max(Demand1);
E2=max(Demand2);
Demand=Demand/E;
Demand1=Demand1/E1;
Demand2=Demand2/E2;
graph=plot([1:length(LoadVariInd(:,1))],Demand, '-oy',[1:length(LoadVariInd(:,1))],Demand1, '-og',[1:length(LoadVariInd(:,1))],Demand2, '-ob');
legend('Industrial Load Profile', 'Residential Load Profile', 'Commercial Load Profile');
set(graph,'LineWidth',1.3);
xlabel('Time (h)');
ylabel('Demand (p.u.)');
xlim([1 24]);
ylim([0 1]);
grid on;

Dear Mr. Thomson
How can I perform a 24-hour power flow analysis (bus voltages, line currents, etc.) of a 33-bus radial distribution system?
