Abstract
The share of renewable energy in the German electricity mix increases steadily, leading to a strengthened impact on the electricity markets. The electricity price is essentially determined by the demand for dispatchable generation, which is mostly equivalent to the difference of load and renewable generation, called the residual load. Data from the German day-ahead market in 2016 shows a strong correlation between the electricity price and the load (r=51%) resp. the residual load (r=74%). Wind power generation correlates to the electricity prices at a level of r=-40%. The strong interdependence of electricity prices and renewable power generation leads to the question whether both share the same statistical properties. This thesis investigates the persistence statistics of the German day-ahead electricity price. A major challenge for this analysis arises from filtering of the strong daily, weekly and seasonal cycles masking the stochastic features. The kurtosis of the waiting time distribution reaches very high values, pointing to a strong persistence of the high series.
