6 FAQs about [No need for intermediate dc energy storage link]

What is an intermediate DC BUS?

The intermediate dc bus can be used to create a dc microgrid for the integration of generation, storage systems and/or loads. In this context, B2B topologies can be analysed as two independent interlinking converters that connect an ac and dc grid (explained in Section 3.3 ), instead of a two-stage ac-ac converter.

What ICS interconnect AC grids?

ICs that interconnect AC grids can be distinguished into one-, two- or three-stage power converters. Regarding one stage ICs, direct matrix converters can be used as shown in Fig. 5 a. Their main advantage is the direct conversion of ac voltage without an intermediate dc buffer .

What is the alternative power route provided by DC-DC IC?

The blue line shows the alternative power route that provides the dc-based power converter. The connection of dc subgrids to a dc grid (tied or isolated from main grid) has also been suggested with the aim of improving efficiency and reliability . Fig. 4. Alternative power flow provided by DC-DC IC in tied microgrids. 3.2.

Are ICS the energy routers of the future?

Therefore, ICs are expected to be the energy routers of the future, smartly connecting and managing the interaction among grids. In the literature several topologies and control techniques have been proposed for this type of converters to transfer power between grids and provide support under contingencies.

Should ICS consider the active power reserves of two interconnected grids?

In this context, it has been highlighted that ICs could consider the active power reserves of the two interconnected grids to support both grids under contingencies.

Should IC be used in AC grid interconnection?

The latter is suggested e.g. in ac grid interconnection where the IC is designed to focus in reactive power compensation and minimize active power transfer to improve overall efficiency and simplify the control of DG systems , .
