Abstract

This thesis presents four research articles, each addressing a specific aspect of the coordination between the electricity markets and the grid. Key questions are how to design prices that accurately capture the unique temporal and spatial characteristics of electricity, and how to allocate costs between competitive wholesale markets and regulated grid operation to incentivize efficient outcomes. This thesis sheds light on how price signals within the electricity system influence system efficiency and economic decision-making. Chapters 2 and 3 are based on numerical models of the wholesale electricity market and the transmission grid, with a particular focus on the integration of flexibility technologies. These analyses investigate how storage investments can be optimally allocated to different locations, and how the flexibility provision of thermal storage combined with heat pumps impacts the electricity system. Chapter 4 broadens the analysis by incorporating the perspective of the grid operator on pricing, analytically deriving the interactions of spot market pricing schemes and network tariffs on consumer decision-making in a dynamic context. Chapter 5 studies whether the economic incentives provided by price signals work as expected in theory and emphasizes the importance of these incentives by showing empirically how price signals guide household investment decisions in residential PV systems in Germany.
