Yes.
A generator is simply a complex power injection and its active and reactive
limits can be anything. Obviously, feasibility requires that PMIN <= PMAX and
QMIN <= QMAX. The only special case is that of a dispatchable load, defined as
a generator with PMAX=0 and PMIN < 0, in which case an additional constant
power factor constraint is added by the OPF.
