Constraints Violation in load flow model

Post by Haithamtaha » 4 months ago

Hello All,

I have an electrical low flow problem using 33 bus distribution system, my objective function is to maximize the installed renewable capacity Wcap(i) at certain buses namely 6,12,18 and 33 following certain demand pattern w1& w2.

eq15 ..
OF=e=sum((i),Wcap(i)* Sbase);

solve loadflow maxmizing OF using MINLP;


The problem is that although I placed a constraint that the installed renewable capacity Wcap(i) at other buses equal zero “ from buses from 1-5, 7-11 and 13-17 and 19-32” as stated below.

Wcap(i) $(ord(i)=1*5.7*11.13*17.19*32)=0;

Pw.l(i,t) $(ord(i)=6.18) =WD(t,"w1")*Wcap.l(i);
Pw(i,t) $(ord(i)=12.33) =WD(t,"w2")*Wcap.l(i);
Pw(i,t) $(ord(i)=1*5.7*11.13*17.19*32)=0;

The solver output gives me non zero for the buses presumed to be zero.

Is there any problem in my statement for the constraint ?


Thanks in advance for your support.
