German nuclear power phase out in 2022 leads to significant reconstruction of the energy transmission system. Thus, efficient identification of practical transmission routes with minimum impact on ecological and economical interests is of growing importance. Due to the sensitivity of Germany's public to grid expansion (especially in case of overhead lines), the participation and planning process needs to provide a high degree of openness and accountability. Therefore, a new methodological approach for the computer-assisted finding of optimal power-line routes considering planning, ecological and economic decision criteria is presented. The approach is implemented in a tool-chain for the determination of transmission line routes (and sets of transmission line route alternatives) based on multi-criteria optimisation. Additionally, a decision support system, based on common Geographic Information Systems (GIS), consisting of interactive visualisation and exploration of the solution space is proposed.

A Less-Effort Method for Spatial Network Planning

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 significant techno-economic solution. In this work, a preprocess stage is employed to reduce the computational effort demanded by line routing.Furthermore, a meta-heuristic algorithm is engaged to solve such a complicated problem. Applying these modifications made it possible to solve SNP for largescale 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 modified versions of the IRAN southeast high-voltage transmission network to demonstrate the capability of the proposed methodology.

In recent years, electricity transmission systems' planning has become a subject of significant discussions worldwide due to increasing investments in renewable power and the need to optimize resources. Planning results directly affect the price of electricity for the final consumers; therefore, it is necessary to determine precise, robust, and relevant plans for the system expansion.Optimization techniques have been successfully employed in several problems associated with transmission line expansion planning, with emphasis on electricity interconnections, routing studies, and tower spotting, among others. The use of these techniques is intended to support planning processes with information that will assist the analyst in the pursuit of defined goals. The present work proposes a methodology based on dynamic programming that seeks to obtain the optimal spotting of transmission towers considering environmental (type of land use, slope, and geotechnical class of the terrain) and engineering characteristics (minimum distance between the electric conductor and ground and tensions supported of each tower type) associated with the problem. The methodology is tested in two different case studies including a real transmission line project with 39 km of extension. The results obtained show, approximately, 3.8% of cost savings obtained using the proposed approach when comparing with the real transmission line project. We also note that it is possible to verify a great similarity between the tower arrangements defined in the real project and the optimal decisions generated by the proposed approach, demonstrating its usefulness as a tool to support decision-making in early stages of investment planning and long-term auctions.
