Transformers Efficiency Variability in Energy Hub Modelling Mohammad Jamjoum, Raneem Mohammad Negry, Zaid Haymoor



This paper presented an energy hub model considering the impact of transformer efficiencies, by taking the difference in transformer efficiency based on the load demand. This can be achieved by taking the transformer efficiency as a dynamic value according to the transformer loading efficiency curve, as the transformer efficiency differs due to the copper losses. The following energy hub model was solved using Mixed Integer Linear Programming (MILP) with a CPLEX solver in GAMS software. Final findings showed that there is only a slight difference in the final overall when taking transformer efficiency variety into consideration for one transformer
