The occurrence of natural disasters imposes potential damage on the power systems. Many methods have been proposed to improve power system resilience by constructing load restoration when the blackout happens. However, disaster like earthquakes may have secondary impacts (i.e., aftershock of earthquake) which would undermine the post-contingency power supply and cause restoration failure. To address such challenge, this paper proposes a Mobile Energy Resource (MER) allocation strategy to restore critical loads by determining the most reliable restoration path against the potential earthquakes. Benefited from the mobility of MER, the restoration paths can always be adjusted according to the real damage of earthquakes as long as there are available paths and capacity. On the other hand, when curtailment is inevitable, critical loads would be optimally shed based on priority. The effectiveness of the proposed strategy is verified by case studies on the modified IEEE 123-node test feeder.
