How fix the generators capacities in runpf after add generator?
I have calculated a standard scheme.
mpc=loadcase('case57');
result_old=runpf(mpc)
Next, I left the power values of generators 2-7 unchanged.
That is, the process of finding the balance relies on generator 1.
I added one reactive power generator gen1 in bus=23
xgen(1,1)=10 % a reactive power gen1
mpc1=mpc
bus_idx=23
gen1(1,:)=zeros(1,21)
gen1(1,1)=bus_idx
gen1(1,2)=0.0
gen1(1,3)= xgen(1,1)
mpc1.bus(bus_idx, BUS_TYPE) = PQ;
gen1(1,4:5)=[20,-20]
gen1(1,7:21)=mpc1.gen(4,7:21)
gencost1(1,:)=mpc1.gencost(1,:);
[mpc2, idx1] =addgen2mpc_ivt(mpc1, gen1, gencost1,'unknown')
result1=runpf(mpc2)
Although in mpc2, the powers of generators 2-8 are the same as I set,
after calculating with the added reactive generator 8
rezult1=runpf(mpc1)
the reactive powers of all generators 2-7 have changed, and the power of the
added generator 8 would not change =10.
I repeat, I want the system to be reactive balanced by generator 1, and the
reactive powers of all other generators to be unchanged, such as in mpc2.
How can I make the reactive powers of generators 2-7 in rezult1 unchanged, i.e.
the same as they are in mpc2?
