Abstract: This paper compares Solid-State Transformers with traditional low-frequency transformers to consider their suitability for temporary power infrastructure in emergency response scenarios and remote locations. While current solid-state transformers do not offer significant weight reductions or cost advantages over low-frequency transformers, they provide approximately 20% volume reduction and superior integration capabilities for diverse power sources and loads. Despite higher initial costs and maintenance challenges, solid-state transformers’ ability to accommodate renewable energy sources, enable direct DC connections and support distributed operations makes them particularly valuable for future applications in disaster recovery and off-grid power systems. The analysis suggests that as solidstate transformer technology matures and gains industry support, it will become increasingly critical for enhancing the flexibility and resilience of temporary power systems in disaster recovery and remote areas. Future research should focus on optimising power electronic components, particularly filter design, to reduce solidstate transformer’s volume and weight and investigate reliability and maintenance requirements in challenging operational conditions.
