•A two-stage model is proposed to design mobile batteries within the microgrid.•The objective is to increase the robustness of the system against severe events.•The model is formulated as MIQP that takes investment and operation decisions.•An integrated power and gas model is used to for electricity and heat energies. In recent years, severe weather-related catastrophes have caused irreparable damages to the body of power systems, which has attracted the attention of planners to increase the resilience of power systems. In line with the goals of this issue, this paper introduces a two-stage programming on the basis of resilience oriented model to design solar panels, micro-turbines, and mobile batteries within the multi energy carrier microgrid to increase the resilience of the system against high-impact events. The propounded framework is formulated as mixed-integer quadratic programming that takes investment decisions at the first stage while optimizing operation variables at the second stage in order to reinforce the resilience of the system. An integrated power and gas model is used to increase the perception of readers about the mutual interactions between electricity and heat energy. Therefore, the availability of fuel and the price of the micro turbine are explicitly formulated and evaluated. One-line diagram of 14-bus coupled micro energy grids is used to investigate the efficiency and proficiency of the proposed model. Comparative studies numerically show that the suggested method helps the microgrid operator in identifying optimal solutions to reinforce the resilience of power system against severe events.
