Hello,

hope someone can help me with this. I will appreciate it because it is urgent.

I have tried to optimize power flow using cone programming. But when I have received errors all the time. It seems that I use the SET which is not defined in the equations.

144 eq3(l)…At(l,b)*W(b)=e=2*R(l,l)*Pr(l)+2*X(l,l)*Qr(l)+R(l,l)*Ploss(l)+X(l,l)*Qloss(l);

**** $149 $149

145 eq4(c,l)…cc(c,l)*X(l,l)*Pr(l)-cc(c,l)*R(l,l)*Qr(l)=e=0;

**** $148

146 eq5(l)…X(l,l)*Ploss(l)-R(l,l)*Qloss(l)=e=0;

147 eq6(l)…Ploss(l)=e=2*R(l,l)*Plossin(l);

148 cone(l)…Plossin(l)+Atr(l,b)*W(b)=C=Pr(l)+Qr(l);

**** $149 $149

How can I write such equations? The dimension of the equations should be correct so how can I index such SET in my equations.

Thanks

JOY
