Abstract: Remote areas are often rich in renewable energy resources, which can be used to produce synthetic natural gas (SNG) at power-to-gas conversion facilities. A balance between gas supply and demand is vital for the efficient and reliable operation of a standalone gas supply system. However, it is generally difficult to guarantee such a balance in a standalone gas supply system. Therefore, a transport tank vehicle is considered as an option for transporting SNG from other areas with sufficient natural gas. Existing studies in this domain have not considered a separate gas supply system for remote areas and fail to provide a robust gas management strategy in an uncertain environment. Thus, this study first introduces a chance-constrained gas management model for the standalone gas supply system. The objective function is to minimize the total operational cost of the gas supply system. An ambiguity set based on the historical wind power data is employed to address the uncertainty caused by the wind power generation. The chance-constrained gas management model is processed via distributionally robust optimization. Then, the gas management model can be reformulated as a mixed-integer linear programming problem. Finally, the proposed model is validated using a case study.
