In the context of distribution grid planning, automated approaches from the electricity sector have already been developed. They focus on removing voltage violations and line overloading, which stem from new installations of PV and wind systems while minimizing the resulting capital costs. The idea is to develop a similar approach for automated gas grid planning. Two methods are studied in this paper. First, a transfer of a capital cost approach from existing power grid planning was implemented. Second, a new operational cost approach in the context of randomized grid defection is introduced. The first method can only be applied in the presence of violated restrictions while the second method can also be used for cost reduction when all parameters are within their limits. The results have shown that the second approach is better suited for the gas grid development in the context of decreasing demand, since the focus lies on minimizing operational costs. In the future a combination of both methods would lead to a generalised framework for minimizing the total cost for strategic gas grid planning.
