Scaled Grid Expansion of Medium Voltage Power Systems with Decentralized Power Aggregates

Today the analysis of the power supply grids shows more and more that the increase of transported power and energy in the last years causes problems concerning the operation of the power grids. A combination of different measures, e.g. grid upgrading, grid toughening, economizing measures, new building of power stations or substations of suitable dimension etc. is necessary to solve those problems. In the following paper a project is introduced where the use of decentralized aggregates instead of building high-voltage power lines is analyzed. Using decentralized power aggregates can help to postpone the expansion of transmission lines and medium high voltage power grids for some years and thus achieving time for discussion with critical citizens and reduce investment costs.
