1. There are two ways to do it. Either convert your loads to dispatchable loads (e.g. use load2disp() to convert them), or simply add positive generators to represent curtailment. In the latter case, you would subtract their output manually from the total generation to get the actual total generation from real generators.
2. If using dispatchable loads, load2disp() will create an appropriate gencost entry for each dispatchable load, and you can customize the value of the curtailed load. If using positive generators to represent the curtailment, simply use a gencost that corresponds to the cost of curtailment.
