We envision a future European transmission power network, which has only power production from renewable sources. With an 8-years-long numerical weather data set of 1h time resolution, the regional wind and solar power production across Europe is determined. This renewable power generation is confronted with the regional consumer loads and determines the fluctuating source/sink strengths of each region. The balancing of the sources and sinks determines the power flow. The latter is calculated within the DC flow approximation, which employs the Laplace matrix of the underlying geometric network, where node-like regions are connected by links. Due to the fluctuating source and sink strengths, the power flows across the links show strong fluctuations. Their characterization allows to roughly estimate the future investment needs into the European transmission power network.
In the second part of the presentation an abstracted network model will be presented, which is able to generically reproduce the results obtained from the weather-driven first part.
