The combination of various energy carriers is an essential factor in power systems to increase endurance and resistance against high-impact events to supply network loads. In this article, a model is presented that deals with the optimal economic operation of the energy hub by increasing the system load resiliency and energy security at the lowest cost. To achieve these goals, energy storage devices and types of energy carriers are used. Furthermore, the loads are categorized as critical and noncritical loads and the highest priority in this article is to supply critical loads. In addition, four scenarios are considered, and each scenario is scrutinized in four steps. Critical load resilience index and energy security indices have been studied in this article, HHI and diversity indices are energy security indices. The operating horizon is 24 hours. In this article, there is a challenge between increasing load resilience and energy security and minimizing costs in the energy hub. In this study, mixed integer nonlinear programming [MINLP] is applied to formulate this optimization problem, which is implemented and solved by GAMS software. The results show that costs rise as critical load resilience increases.
