hi ray thanks for your quick responce.i want to explain all programm to u so 
you can help me in defining constants this is first function line in which 
case30 takes variables values.function mpc 
=case30(cap1,cap2,cap3,cap4,cap5,cap6,tap) ; then capacitors are defined as  if 
cap1==1c1=0.6else c1=0endif cap2==1c3=0.6else c3=0end
then capacitors are defined in bus data as 2 1 w*PL2_day(seq) w*QL2_day(seq)-c1 
0 0 ...and oltc tap in branch data as1 2 0.11 0.32 0 130 130 130 tap 0 1 -360 
360; now is it correct to define data as you explained   mpc.bus(cap1_busidx, 
BS) = cap1(hr);  i want to know that i have to define values as    mpc.bus 
(cap_busidx,BS)=cap1(1 0 0 1 0 1 0); for 24 hours

Without more information about your setup, I’m afraid it’s a bit difficult to 
say exactly how to accomplish what you want. The case30() function included in 
MATPOWER is a simple case file that does not take any arguments. It seems as if 
you are probably attempting to update some capacitor and transformer tap 
parameters of the case30 to run a slightly different power flow or OPF for each 
of 24 hours. That can be done by loading the case30 and then modifying the 
appropriate elements in the bus and branch matrices manually based on the cap 
and tap values you have for that hour, something like the following ...
define_constantsmpc0 = loadcase('case30');for hr = 1:24    mpc = mpc0;    
mpc.bus(cap1_busidx, BS) = cap1(hr);    mpc.bus(cap2_busidx, BS) = cap2(hr);    
mpc.branch(xfmr_idx, TAP) = tap(hr);    results(hr) = runpf(mpc);end
