6 FAQs about [The connection between active distribution network and microgrid]

Can a microgrid form a distribution network?

Distribution networks have undergone a series of changes, with the insertion of distributed energy resources, such as distributed generation, energy storage systems, and demand response, allowing the consumers to produce energy and have an active role in distribution systems. Thus, it is possible to form microgrids.

Does a microgrid sell power to the ADN?

It can be found that the network loss of the microgrid shows an apparent downward trend after it is integrated into the ADN. It shows that the network loss is effectively reduced after the microgrid is connected to the grid. As can be seen from the figure, at this moment, the microgrid sells power to the ADN.

Should microgrids be added to active distribution grids?

From the results presented in Table 2, it can be seen that adding microgrids to active distribution grids, in general, is beneficial in terms of economic and technical aspects because the costs are not greatly increased (scenarios 1 and 2). The microgrids have enough energy and try to contribute to the grid by injecting energy.

How a microgrid is connected to an ADN?

When microgrids are connected to the ADN, the operational capacities of all flexible resources, along with the power exchanges between the ADN and the microgrids, are considered decision-making parameters. Utilizing forecasts for generation, demand, and PV output, a comprehensive scheduling strategy is formulated every 24 h.

Do microgrids and other distributed resources reduce power losses and operation costs?

So, in general, both microgrids and other distributed resources that can be incorporated into the active grid, if their operation and the DERs were appropriately optimized/allocated, tend to decrease power losses and operation costs of active grids with microgrids and other DERs.

How is network loss determined in ADNs and microgrids?

In ADNs and microgrids, the rational distribution of active and reactive power is determined by the power flow calculation, and the network loss is closely related to the power flow calculation. Figure 16, above, reflects the network loss before and after the incorporation of the microgrid into the ADN. The comparison figure is shown in Figure 16.
