Modular Matrix Converter Based Solid State Transformer for smart grids

The proposed Modular Matrix Converter Based Solid State Transformer is simulated and the obtained results show that it is able to regulate the secondary side voltage and frequency, even in a bidirectional power flow operation scenario, allowing power factor correction in the local MV connection, and providing mitigation capability of voltage sags and swells up to 20%, therefore improving power quality in the smart grid.
