Climate change mitigation strategies such as the German Energiewende require linking vast numbers of new power generation facilities to the grid. As the input from many renewable sources is rather volatile, depending on how much the wind blows or the sun shines, there's a higher risk of local power instabilities and eventually blackouts. Scientists from the Potsdam Institute for Climate Impact Research (PIK) now employed a novel concept from nonlinear systems analysis called basin stability to tackle this challenge.
