Abstract

The thesis at hand comprises five research papers and seeks to shed light on three major subfields of the energy transition, all of which may be positioned within the topic of short-term power system flexibility. Chapter 2 contains an analysis of the impact of an advanced metering infrastructure on residential electricity consumption. We find that additional informational feedback provided by smart meters triggers a significant reduction of the average residential electricity consumption of approximately 6%. The impact in question is only significant in non-heating periods. Chapter 3 focuses on a beneficial interaction of photovoltaic generation units and electric vehicles in the light-weight transport sector. A bottom-up simulation approach has been developed to model the driving and charging demand of electric vehicles. The simulation results show that, on a household level, smart charging strategies oriented to renewable energy sources may allow for higher shares of self-consumption. On a system level, reducing the impact of the electric vehicle charging demand on the peak load is a coordination problem. In Chapter 4, we analyze the underlying drivers of the high price volatility observed in German electricity markets with sub-hourly contract duration. We find that the high volatility is mainly driven by sub-hourly variations of renewable generation and electricity demand as well as restricted participation in the German intraday auction. We analyze the underlying drivers of restricted participation within Chapter 5 and identify the lack of sub-hourly market coupling as being the most relevant driver. Finally, Chapter 6 focuses on the economic analysis of price premiums in German short-term electricity markets where the underlying merit order exhibits a discontinuous shape. Based on a theoretical model, it is suggested that non-convexities in only a subset of sequential markets may lead to price differences at equilibrium.
