In this thesis, a methodology is developed to optimally position stationary large-scale batteries in distribution grids from a technical and economic point of view. The battery system will be used where the prompt grid expansion costs are maximum with the increasing expansion of decentralized renewable energy plants. With the help of an algorithm, potential locations in different distribution grids are compared with each other and a ranking is created. The methodology is applied to eleven medium-voltage and 80 eligible local grids in a grid area in southern Germany. Only low-voltage locations come into question.
By analysing the grid parameters of the most promising locations, three general selection criteria can be developed on the basis of which a pre-selection of potential battery locations can be made in a simplified manner in the future. This provides distribution system operators with a tool with which they can determine potential battery locations in their grid area without complex simulations.
