The problem presented here is related to the use of stand-alone diesel gen-sets and its high specific fuel consumptions when operates at low loads. The variable speed gen-set concept is explained as an energy-saving solution to improve this system efficiency. This paper details how an optimum fuel consumption trajectory based on experimentally Diesel engine power map is obtained.engBrake specific fuel consumptionDiesel engineOptimal BSFC trajectoryPower mapVariable speed gen-setconference object10.1109/CPE.2015.7231088
