Abstract
In this study, a decision-support index is proposed for the proper operation of a grid-connected smart microgrid, aiming to establish a trade-off between microgrid resilience and operational cost under Storm scenarios accompanied by the simultaneous outage of multiple distribution lines. The studied microgrid, benefiting from smart infrastructure, is capable of implementing demand response programs, including bidirectional power management in electric vehicle (EV) parking facilities and automatic network reconfiguration. To quantitatively assess system resilience, a novel quantitative–technical index is developed that considers not only the amount of unserved load but also voltage deviation as an indicator of power quality in microgrid operation. Moreover, to enhance the realism of the proposed model, uncertainties associated with renewable energy generation are incorporated within a probabilistic framework. Simulation results demonstrate that the coordinated application of network reconfiguration and demand response programs leads to a 76.6% reduction in the proposed resilience index and an 86.9% decrease in voltage deviation. These findings confirm the effectiveness of the proposed approach in enhancing technical resilience as well as achieving stable and cost-effective operation of smart microgrids under critical conditions.
