New Topology and Functionalities of a Hybrid Transformer for Flexible Operation of Distribution and Transmission Systems

Due to the progress of the energy transition, an increasing percentage of converter-based grid components leads to a change of the grid characteristics. Increased controllability is able to improve the operation of future power grids and contribute to a stable grid operation. This contribution presents the magnetically integrated concept of a hybrid transformer. This concept enables increased voltage and current scalability in terms of converter components, increased controllability of the distribution grid as well as additional system services. In order to implement these extended properties of the transformer, a modification of the magnetic core as well as the winding configuration is necessary.
