6 FAQs about [Energy storage system three-phase transformer]

Does a three-phase solid-state transformer improve power quality?

In References 103, 110, a mathematical model of a three-phase solid-state transformer is presented that investigates the effect of SST on power quality improvement.

What is a battery energy storage system?

Battery energy storage systems based on bidirectional isolated DC-DC converters (BIDCs) have been employed to level the output power of intermittent renewable energy generators and to supply power to electric vehicles. Moreover, BIDCs use high-frequency transformers (HFTs) to achieve voltage matching and galvanic isolation.

What is battery energy storage system (BESS)?

Recent works have highlighted the growth of battery energy storage system (BESS) in the electrical system. In the scenario of high penetration level of renewable energy in the distributed generation, BESS plays a key role in the effort to combine a sustainable power supply with a reliable dispatched load.

How to choose a battery energy storage system based on a DC-DC converter?

Battery energy storage systems based on a DC-DC converter should have bidirectional power transfer capability, galvanic isolation, high-power density and high efficiency. The power density of a DC-DC converter can be increased by applying a higher switching frequency ( ) to downsize the magnetic components.

Why do we need a transformer in a power system?

In general, in the power system, traditional transformers are used to step up/step down the voltage. But these transformers do not have the ability to compensate for voltage sag and swell, reactive power, fault isolation, and so on. But with SST we will be able to overcome these drawbacks.

What are the advantages of a solid-state transformer?

In Reference 106, a new model for solid-state transformers is proposed; one of its advantages is better power factor correction and voltage regulation. The proposed model eliminates voltage sag and voltage swell using the existing STATCOM in the distribution network.
