ISLOAD Checks for dispatchable loads. TORF = ISLOAD(GEN) returns a column vector of 1's and 0's. The 1's correspond to rows of the GEN matrix which represent dispatchable loads. The current test is Pmin < 0 AND Pmax == 0. This may need to be revised to allow sensible specification of both elastic demand and pumped storage units.
