Portable battery devices (PBD) can enhance the resilience of distribution networks against crises by providing realistic backup resources and enabling substantial geographical flexibility across the network. In this study, a two-stage preventive planning approach is proposed to optimize PBD deployment under both normal and emergency conditions. In the first stage, a mixed-integer second-order conic programming model with binary recourse options is formulated to determine the preselected locations of PBD, considering various risks under normal operating conditions. In the second stage, a robust two-stage optimization is applied to redirect the deployed PBD, creating dynamic microgrids capable of handling operational failures with the assistance of a progressive hedging algorithm. Finally, a hybrid allocation strategy is introduced to satisfy requirements related to self-sufficiency, operational conditions, and grid topology. The effectiveness of the proposed two-stage allo- cation method is demonstrated on multiple modified networks. In all abnormal scenarios, the lost load with and without PBD is compared: the average lost load without PBD is 497 kWh, with stationary PBD it decreases to 322 kWh, and when mobile PBD is used, it is further reduced to 275 kWh.
