I am replying to the MATPOWER-L mailing list, which is what I think you intended. (You sent it to the list owner, not the list).
MATPOWER does not currently implement what you are looking for, but it should be fairly straightforward to implement it yourself. You will simply need to scale the dispatches of the conventional generator based on the total load before running the power flow.

In my project I am using IEEE-39 bus system and to this test case I am integrating renewables at particular buses, before integrating, I am decoupling the ieee-39 bus system into three regions. So each region will have one renewable(wind) generator as fixed source. When I decoupled the system into three different regions, I assigned new slack bus for each regions based on the max capacity generator. I am running the system for few time intervals, so, at each time intervals there is generation from wind generator, which is been integrated into the system and the rest of demand is supplied by the conventional generators, so when I am running the Powerflow for this, I have multiple cases. Case 1: load demand in one region is 2200 MW Generation from renewable is 1100MW The rest of the demand is fulfilled by the three conventional generators. Gen 33 is supplying 612 MW Gen 34 is supplying 508 MW Gen 38 (which is slack bus in this region) is supplying 22.54 MW. So, if you see the Gen 38 is going below the limit when I am running Powerflow using runpf command. So, here what I want to do is instead of gen 38 going that low, I want all the three conventional generator in this region to cooperatively supply the rest of the demand which is 2200-1100 MW=1100MW. I want to know is there any way in MATPOWER where I can have multi control on all the generator, so that I set it up in a way where the demand in the system should be fulfilled by all three generator. I have few other cases when there is more input from the wind generator and in that case the supply from the Gen38 is going in negative. So, if anyone can help me on this, it will be highly appreciated. Regards, Abdul Shafae Mohammed Graduate Student Dept. of Electrical Engineering Tuskegee University.
