This paper presents a method to solve spatial network planning (SNP) in power systems expansion. SNP is an integration of transmission expansion planning (TEP) and optimal line routing problems. In fact, SNP considers the impacts of lines routing on the network power flow. Therefore, it can exploit such impacts
to attain a signicant techno-economic solution. In this work, a preprocess stage is employed to reduce the computational eort demanded by line routing. Furthermore, a meta-heuristic algorithm is engaged to solve such a complicated problem. Applying these modications made it possible to solve SNP for large-
scale systems with high-resolution rasterized maps. The proposed method is applied to a 3-bus system, an 18-bus test system as well as the original and modied versions of the IRAN southeast high-voltage transmission network to demonstrate the capability of the proposed methodology.
