Abstract:
Deploying weather-dependent renewable energy resources in the distribution electricity grid can increase the demand for energy flexibility. Couplings with other energy sectors can help meet this demand, resulting in a multi-energy system. Controlling these coupled grids is challenging due to the diverse requirements of various stakeholders, particularly prosumers, and the significant challenges of operating resiliently in such non-homogeneous grids. The coupling points connecting the different grids may introduce difficulties and opportunities. This is especially true when the grid is affected by high-impact events, which result in lower overall system performance. A self-organized approach is advantageous for coping with such emergencies in this complex system due to its capability to distribute actual grid control while maintaining a decentralized system structure. This approach can be implemented by designing a system in which agents control the different actors.
This thesis contributes to the design and implementation of such a system for grid emergencies. For this, the behavior of agents in a volatile coupled network is analyzed, and different collaborative strategies are evaluated to determine an appropriate approach. In the next step, the multi-energy grid is physically modeled using steady-state equations and analyzed for its resilience properties and the quantification of the resilience. At last, an approach for self-organized recovery is developed. This approach involves topology reconfiguration and a self-organized multi-level sector, as well as cross-sector optimization utilizing gossiping and the alternating direction method of multipliers.
