EMS for fuel saving in an isolated hybrid system (solar/diesel/battery)

This paper presents an energy management system (EMS) for a fuel saving application in an isolated hybrid system (solar/diesel/battery) that takes into consideration the battery degradation. A simplified model is used for estimating the battery degradation. The operation of the hybrid system, which it is carried out by the EMS, is based on a rolling horizon strategy to minimize fuel consumption and degradation. The optimal operation of the system is solved as an optimization problem in MATLAB to obtain the schedule of the battery energy storage system (BESS) while estimating its degradation. Moreover, the energy produced by each generation system is calculated and compared to a configuration without BESS.
