Design of portable energy distribution system for post-disaster emergencies

This thesis focuses on developing a technical model for providing emergency electricity to temporary shelters and search and rescue zones in the aftermath of natural disasters, particularly where existing power distribution networks have lost functionality. The primary aim is to minimize the impact of power outages following disasters and ensure energy supply security by evaluating alternative network structures in terms of technical feasibility and economic efficiency. The initial chapters of the study present a comprehensive analysis of the effects of disasters on energy infrastructure, the seismic risk profile of Türkiye, and the structural features of the national electrical grid. Subsequently, a technical overview of electricity generation and transmission systems is provided, with a focus on medium and high-voltage networks, network types, and design principles. In the application phase of the thesis, two scenarios were developed: one addressing container settlements and the other supporting search and rescue operations. Load estimations were performed, and suitable materials and network designs were proposed accordingly. In both scenarios, reliable, rapidly deployable, and disaster-adapted electrical networks were designed, incorporating load forecasting and transformer selection to offer alternative energy supply solutions. As a result, the study demonstrates that ensuring reliable energy access in post-disaster temporary accommodation and operational zones is achievable through effective planning and appropriate network design. This thesis thus provides a practical technical guide for the post-disaster restructuring of critical power infrastructure.
