6 FAQs about [Iceland interconnected microgrids]

How do interconnected microgrids fulfil multienergy demands?

In this framework, the interconnected microgrids not only fulfil the multienergy demands of with local hybrid biogas-solar-wind renewables, but also proactively trade their available multienergy and communication resources with each other for delivering secured and high quality of services.

How are microgrids interconnected?

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: The management and control of the network of microgrids are performed by the MA in a centralized way.

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.

What is a microgrid system?

The system is an extension of the case study presented in Chap. 4. Each microgrid i is composed of a battery, a hydrogen system (a storage system, electrolizer, and fuel cell allowing bidirectional power flows), renewable generation (solar and wind), a local load, interconnection with other microgrids and also to the grid (see Fig. 8.7 ).

Should microgrids be prepared to operate independently of the utility grid?

But in addition, microgrid networks should be prepared to operate independently of the utility grid in case of faults and congestion. Networks of microgrids with energy storage systems require new architectures and specific techniques to address their management and control.

Why should a microgrid be integrated?

One of the most common issues is that agents of the different microgrids can be different and independent, hindering the system management. 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.
