6 FAQs about [Method for constructing interconnected microgrid groups]

Why is interconnection of microgrids important?

The interconnection of microgrids can improve reliability, reduce emissions, expand energy options in the future power system, add redundancy, and increase grid security. The normal operation of the network of microgrids should be oriented to achieve a better economic return with respect to the single operation of the microgrid.

How are microgrids connected?

The elements of each microgrid are connected by a Local Area Network (LAN) of fieldbus. Due to the geographical distribution, the microgrids are interconnected among them and with the aggregator using a Wide Area Network (WAN). Different possibilities are as follows:

What are the functions of microgrids?

It covers functionality of microgrids including operation in grid-connected mode, the transition to intentionally islanded mode, operation in islanded mode, and reconnection to the grid, specifying correct voltage, frequency, and phase angle.

What is the energy management problem of interconnected microgrids?

This chapter is devoted to the energy management problem of several interconnected microgrids. EMS of a network of microgrids must determine the power flows inside each microgrid and with the main grid (as in Chap. 4), but also the energy interchange among them. This is an extension of a single microgrid EMS and MPC is an alternative to solve it.

Should a microgrid be integrated with a utility grid?

So the integration of the different agents will always be aligned to reach a better performance in the energy management problem than operating as a single microgrid. But in addition, microgrid networks should be prepared to operate independently of the utility grid in case of faults and congestion.

What is a basic management system for three interconnected microgrids?

In order to evaluate different algorithms, a basic management system for three interconnected microgrids ( \ (MG_1, MG_2\) and \ (MG_3\)) will be considered. The system is an extension of the case study presented in Chap. 4.
