The development of power systems and the move to smart grid have increased the need for new technologies. In this regard, Solid State Transformers (SST) have been proposed as a suitable alternative to conventional transformers. SST is offered as a tool to meet the requirements of the smart grid. SST are among the equipment based on power electronic converters that in addition to better performance than conventional transformers provide a variety of other services. Studies show that the various characteristics of solid-state transformers have led to much consideration as potential transformers in smart grid applications, the integration of distributed generation sources, modern traction systems, and so on.

SST incorporate power semiconductor components, control circuits and high-frequency transformers, offering bi-directional power flow control, harmonics reduction, and many other benefits. They allow conversion from Alternate Current (AC) to Direct Current (DC), DC to AC and DC to DC on different voltage levels. They are designed to support power system transformation towards more flexible AC and DC mixed system configurations, facilitating the integration of renewable energy sources close to DC loads.

This new grid architecture can also benefit applications such as data centers, wind farms, solar plants, hydrogen generation and electric vehicle charging infrastructure. As a small island nation, the country has always sought innovative solutions to stretch its land options, while balancing commercial needs and sustainability. SST are multifunctional and will allow users flexible control on the amount of power that is distributed to networks. By doing away with multiple separate equipment required by current conventional transformers, we also save on land-use, making the SST an attractive solution for a more efficient electricity grid.
