6 FAQs about [Smart microgrids need to be equipped with transformers]

Why do we need a smart grid and a microgrid?

The competitive landscape among energy providers and distributors has empowered consumers to not only save money on their energy bills but also incorporate sustainable energy sources into the grid. To efficiently manage electricity distribution, deregulated power systems must include a smart grid and microgrid (MG).

Can solid-state transformers be used in smart grid applications?

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.

Are microgrids the future of power supply?

The development of microgrids (MGs) and smart grids, as creative alternatives to the traditional power grid structure, has prepared the way for the development of the future of power supply. RE is required because of its multiple benefits, including being an inexhaustible supply of free energy with no emissions.

What is a smart grid?

Smart grid is a relatively new approach to the future of the power system that pursues several goals such as distributed operation and control, stability increase, increasing sustainability and reliability, improving power quality, expanding effective and active loads, and so on.

What is a SST based microgrid?

Hence, SSTs were introduced as an alternative to traditional passive transformers in microgrids. Figure 7 shows the architecture of a SST-based microgrid, in which the SST provides three interfaces to the system (primary, secondary, and DC side). Roughly, the SST acts as a three-port power router.

What are the applications of SST in the future smart grid?

Moreover, another application of SST in the future smart grid is its use as a tool for measuring high current and voltage, such as current transformers (CT) and potential transformers (PT), and can lead to more accurate and real-time measurements, and on the other hand, can lead to the integration of equipment in the form of SST structure.
