Why variable speed generators? When feeding variable loads, the power demand from the generator is also variable.  Constant speed generators are tuned to operate at high efficiency at their full load demand.  For a variable load, engine speed should also vary according to the load demand, where optimum fuel is consumed for that particular load level.
