?Hi Shri,
>You can model it as a generator in MatPower with a negative Pmin, Pmax and a >positive Qmin, Qmax. My thought was that if I do this Matpower won't recognize it as a dispatchable load and hence won't maintain a constant power factor - perhaps I'm mistaken here, I'll gave it a go though and it seems to be working. >What kind of load is this???? Honestly, I don't know. See the load at bus 9 in the attached model. It is one of the test cases supplied with MATPOWER so I assume it is not in error.

You can model it as a generator in MatPower with a negative Pmin, Pmax and a positive Qmin, Qmax. What kind of load is this??? Shri For example, buss 9 in the 39 bus example, case39.m has a reactive demand of -66.6. Setting Qmin to -66.6 would not model this correctly but If I set Qmin to 66.6 and Qmax to 0 the OPF does not solve. If I set Qmin to 0 and Qmax to 66.6 I don't think matpower recognizes this as a dispatchable load. ?
