Resilience assessment of mobile microgrid scenario for supporting critical infrastructure post-disaster

Natural disasters (ND) often disrupt traditional power grids, leaving critical facilities such as hospitals, emergency response centers, and communication hubs vulnerable to extended outages. Mobile microgrids (MMGs) are essential for ensuring the resilience of critical infrastructure during and after disasters. This research explores the resilience assessment of using mobile microgrids to enhance energy resilience for critical infrastructure during and post disasters. It focuses on whether a standardized mobile microgrid, housed within a Truck and weighing limit, can adequately support small critical sites with an average 10 kW load. The analysis assumes scenarios where natural disasters may cause power outages, and existing microgrids are present but lack redundancy to justify the creation of bespoke systems for individual critical loads. To assess the robustness of the suggested mobile microgrid, a system that combines a natural gas generator (NGG), photovoltaic (PV) electricity, and a battery energy storage system (BESS) is designed within the logistical and physical limitations of a typical mobility truck (MT). HOMER Grid software models random outages that can last up to 72 hours and evaluates the architecture using Global Horizontal Irradiance (GHI) data and a randomized 10 kW load profile from Lombok Island, Indonesia. The outcomes demonstrate how the system can supply essential loads using less fossil fuel. According to the results, standardized mobile microgrids provide a practical and quickly deployable alternative for restoring critical infrastructure services in the case of a disaster.
