The power system in Europe is undergoing a rapid transition with the expansion of renewable capacity and a decrease in dispatchable conventional technologies. An important part of planning for the power system is ensuring the security of the electricity supply. The focus of the work within the dissertation is to investigate the role of interconnectors in maintaining the security of the electricity supply. With this focus in mind, three sets of research questions are answered: How to assess the Security of Supply in a power system? With the decrease in available conventional generation capacity, how much and what new investment would be required? What role do grid interconnections play in maintaining the security of supply? These research questions are answered by starting with a framework of analysis which classifies various aspects relevant to ensuring the security of electricity supply into uncertainties, systematic risks and specific risks. A scenario-based analysis has been carried out by using a deterministic capacity expansion model to investigate systematic risks and capacity expansion requirements. This is followed by a Monte-Carlo-based stochastic generation adequacy assessment to assess specific risks. The results show significantly reduced capacity requirements from cross-border reliance in maintaining generation adequacy. Furthermore, the interaction between the increase in renewables, capacity expansion requirements and generation adequacy are analyzed.:1. Introduction
