  In this paper, we propose a novel Health-Focused Optimal Power Flow (HF-OPF)
to take into account the equipment health in operational and physical
constraints. The health condition index is estimated based on the possible
fault characteristics for generators and batteries. The paper addresses the
need for understanding the relationship between health condition index and the
operational constraints in OPF problems. Such a relationship is established
through Finite Element Method (FEM)-based simulations. The simulations for
generator and battery faults indicate the presence of an inflection point after
which effect of fault becomes severe. A microgrid system is used to illustrate
the performance of the proposed HF-OPF. The results show that health condition
inflicts high cost of generation and can lead to infeasibility even with less
critical faults.
