• A novel approach to modeling the energy hub for microgrid is presented.
• The proposed model avoids the limitations identified for the original hub model.
• The proposed energy hub model has been verified by steady-state calculations.
• Possible application of the presented model has been identified.

The paper deals with a novel approach to modeling the energy hub for microgrid representation in steady-state analysis. The presented model enables to avoid some limitations identified for the conventional (original) energy hub model. First a mathematical model has been formulated with the use of graph and network theory. Then a proposed model has been verified by steady-state calculations for selected microgrid operation scenario and exemplary energy hub structure. Finally a possible application of the presented model has been identified and future works have been widely discussed.
