Wind and photovoltaic systems play a central role in the decarbonization of European power generation. Their infeed, which is subject to forecast errors, increasingly requires the use of control reserve, resulting in rising costs for ancillary services. Based on the recently adopted Electricity Balancing and System Operation guidelines, an organized load-frequency control across control areas is being initiated on the European level. Cooperation resulting from this can indeed make efficiency increase possible but at the same time can have a negative impact on power trading and security of supply. This must be assessed if cooperation is to be further intensified. The thesis evaluates various approaches to cross-border load-frequency control. Limited transmission capacity and the resulting interactions with electricity power trade prove to be a key question. To evaluate various concepts quantitatively for dealing with transmission capacity as well as their effects on the markets for power and control reserve, simulation and optimization methodologies are developed and presented. Analyzes show that with an organized load-frequency control across control areas economic efficiency gains can be realized without negatively affecting security of supply. The potentials strongly depend on the handling of transmission capacity. In the case of direct competition, the use for power trading is usually more economically efficient than for an exchange of control reserve. The greatest potential is promised by a probability-based estimation of the available transmission capacity after closing of electricity trading This can avoid a reservation and eliminate the risk of high opportunity costs of lost electricity trading. In return, forecast uncertainties must be evaluated.
