There is 3 generators with the actual power: A is 30kW, the generator B is 100kW and C is 50kW. All 3 generator needs to be equally 60kW and can't exceed 100kW. But I can only do these power switch: transfer 30kW from A to B, 10kW A to C, 20kW B to A, 20kW B to C and 10kW C to A . I can only do 3 switch.
