Active Thermal Control and Digital Twin-based Observation of Hybrid Grids-Feeding Smart Transformers
The increasing integration of distributed renewable energy sources and electric vehicle charging systems into the electricity grid poses challenges in handling high generation and demand variability. The utilization of a hybrid distribution system - which embeds dc grids inside the existing ac grid structure - could combine an efficient integration of renewable energy sources and electric vehicle charging stations via dc grids with the established protection mechanisms of ac grids. The provision of a flexible ac and dc distribution and further possible grid services can be enabled by the Smart Transformer, which is a power electronics-based transformer with advanced control functionalities. However, two major concerns impeding the adoption of Smart Transformers for the distribution system are the efficiency and reliability. This work contributes to the advancement of efficiency and reliability in the Smart Transformer by proposing an optimized Smart Transformer topology for efficiently establishing hybrid grids, developing digital twin approaches for observing the thermal behavior of power modules, and elaborating on active thermal control approaches essential to support a reliable Smart Transformer operation.
