Here’s an example, where gencost is set to minimize losses, and the legacy user
costs are set to a quadratic cost on all voltage deviations from 1, where w is
a weight that controls the relative importance of the two objectives.

define_constants;
w = 10;
mpopt = mpoption('verbose', 2);
mpc = loadcase('case9');
% set uniform linear cost to minimize losses
mpc.gencost(:, NCOST) = 2;
mpc.gencost(:, COST) = 1;
mpc.gencost(:, COST+1:end) = 0;
nb = size(mpc.bus, 1);
ng = size(mpc.gen, 1);
mpc.N = sparse(1:nb, nb+1:2*nb, 1, nb, 2*nb+2*ng);
mpc.fparm = ones(nb, 1) * [2 1 0 1];
mpc.Cw = w * ones(nb, 1);
r = runopf(mpc, mpopt);

Can I get some examples of references to solve this problem? I have used
optimization techniques to solve loss minimization using as DG real power as
injected negative load with variable location.

The OPF in the current MATPOWER does not include transformer taps or switched
shunt settings as control variables. You can minimize power losses by setting
all of the generator active power costs to an identical constant. If you want
to combine that with some voltage deviation minimization, I think you should be
able to do that using the (legacy) user-defined costs described in Section
6.3.3 and 7.1.3.

The objective is to minimize power losses and voltage deviation.
The control variables are 1- generators' voltages, 2- transformer tap settings,
3- injected Q by shunt capacitor.
The paper in the attached link describes the problem.
