This paper explores the application potential of new solid - state transformers in smart grids. By analyzing the differences between them and traditional transformers, it reveals their significant advantages in improving power quality, enhancing grid stability, and enabling intelligent management. Solid - state transformers can not only optimize voltage regulation and power factor correction, but also effectively support the integration of renewable energy sources, providing strong technical support for the development of smart grids. However, cost and technical challenges still remain the main obstacles to their widespread application. Nevertheless, with technological advancements and increased market acceptance, solid - state transformers are expected to become an important force in promoting the development of smart grids towards a more efficient and reliable direction.
