Fluctuation analysis of German electricity power production: Comparison of classical and renewable sources — Hynek Lavicka1 and •Jiri Kracik2 — 1Czech Technical University in Prague, Faculty of Nuclear Sciences and Physical Engineering, Department of Physics, Břehová 7, CZ-11519 Prague 1, Czech Republic — 2Charles University in Prague, Faculty of Social Sciences, Institute of Economic Studies, Opletalova 26.

We perform analysis of time series of electric power load production by type of power plant in Germany between 2010 and end of 2014. We report presence of 1/f noise with additional peaks for most of time series. Performing test statistics we obtain indication of presence of autocorrelations. Detailed analysis using MFDFA allowed to distribute electric power sources into three groups according to presence of type of autocorrelation. Solar, wind and gas power plants and other renewable enegy sources exhibit anti-persistent behaviour while nuclear power plants, combined heat and power and Run-of-the-river hydroelectricity show persistent behaviour and finally, coal power plants mostly present uncorrelated behaviour. All sources share wide multi-fractal spectra of correlations while distribution multi-fractal spectrum is rather narrow and the distribution function deviates from Gaussian distribution.
