Resilient Energy Management Framework for Networked Microgrids Using Integrated Hydrogen Systems and Demand Response

This paper presents a novel resilient energy management framework (RAEMF) for networked microgrids (NMGs) to enhance their operational resilience during extreme circumstances. The proposed framework coordinates renewable energy sources, controllable distributed generators (CDGs), demand response programs (DRPs), and hydrogen systems effectively through different preventive strategies and advanced optimization. In the proposed model, leveraging predictive scheduling, critical preparedness is ensured by fully utilizing hydrogen storage capacities, prescheduling CDG commitments, and dynamically adjusting demand-side resources. The proposed framework is designed as a mixed-integer linear programming (MILP) problem that evokes proactive measures through capacity-based signaling mechanisms. The framework demonstrates its functionality through testing on a system made up of four interconnected microgrids, that are connected to utility grids while supplying power to critical loads during extreme disasters. The results demonstrate that the suggested method guarantees the energy supply's reliability by maintaining critical load coverage. Moreover, the proposed approach minimizes operational costs while reducing dependence on the upstream grid during the extreme disasters. This work contributes by introducing a novel power management through coordinating the operation of hydrogen systems, CDGs, and DRPs thereby enhancing NMG resilience and operation costs.
