Buchtitel: ETG Congress 2015 – Die Energiewende
Energy systems are undergoing substantial changes as more and more energy is generated by distributed power plants and from renewable energy sources. This decentralization and intermittency of generation has a significant impact on low voltage power grids. To assess the effects on the grid, we present a scenario that comprises a number of prosumers in a suburban low voltage grid. Furthermore, by applying a comprehensive bottom-up simulation of households, we show that in-house optimization can effectively reduce stress on power grids. This in-house optimization is realized by energy management systems that optimize generation and consumption within households with respect to cost minimization. The optimization is performed considering current tariffs and complying with user preferences.
