Existing generating facility is 60MW + 60MW 50Hz supplying a maximum 90MW load. Both generator are identical with same droop characteristic of 6%. There is foreseeable increase in
load by 30MW. New generator selected is 100MW with droop characteristic 5%. Please advise which method has better performance, replace both the generators (i.e. 100MW + 100MW) OR replace one generator only (100MW + 60MW)?
