6 FAQs about [Substation AC DC Microgrid]

Are microgrids AC or DC?

The aforementioned elements and issues mainly depend on the technology (AC or DC) of the distribution line of the microgrid. At the same time, because microgrids can be connected to AC and DC transmission systems ( Fig. 2 - ①) with different advantages and disadvantages (Section 3 ).

What causes power quality issues in a hybrid ac/dc microgrid?

In a hybrid AC/DC microgrid (MG), power quality issues arise when an unbalanced load connects to the AC subgrid, which are not confined to the AC subsystem but extend to affect the DC subsystem as well. This paper investigates the potential power quality issues caused by AC imbalance, including DC voltage fluctuation and AC current harmonics.

How many transformer substations are in a microgrid?

The general microgrid of the CE.D.E.R. centre has a medium voltage grid (15 kV) in which eight transformer substations can be found that adjust the voltage from 15 kV to 400 V three-phase low voltage. For the TIGON demonstration, we will focus on an area within the centre's facilities called PEPA II.

Are there hybrid microgrids that combine AC and DC distribution lines?

There are also hybrid microgrids that combine AC and DC distribution lines that are controlled separately , , , . AC microgrids can present different distribution types: single phase ( Fig. 2 - ③, 3a), three phase without neutral ( Fig. 2 - ③, 3b) and three phase with neutral ( Fig. 2 - ③, 3c).

How to improve power quality in AC microgrids?

Some solutions have been proposed in order to improve power quality in AC microgrids . DC distribution networks ensure a higher power quality to the customers than in AC distribution network and facilitates more DGs connection .

Are microgrids a good solution for distributed generation?

Microgrids are a suitable, reliable and clean solution to integrate distributed generation into the mains grid. Microgrids can present both AC and DC distribution lines. The type of distribution conditions the performance of distribution line and implies different features, advantages and disadvantages in each case.
