Hi, Does this mean that if I model a dispatchable component like -5MW <= P <= 5MW with a corresponding cost, then the OPF decides whether the P takes on a positive ("generator" mode, P is injected) or a negative ("load" mode, P is drawn) value depending on the system scenario? Cheers, Ronald

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
