6 FAQs about [Decentralized microgrid Greece]

What is the difference between decentralized and distributed microgrid control?

The decentralized control is mainly applied in primary control, and distributed control is widely discussed in islanded microgrids. By leveraging different controller design strategies, the distributed and decentralized microgrid control can guarantee one or multiple control performances, however, along with noticeable weaknesses.

Why is a decentralized Microgrid Controller architecture important?

Using multiple sources with differing characteristics and native constraints makes it a challenge to control the microgrid. Compared to the traditional central controller approach, a decentralized microgrid controller architecture has benefits including resiliency to asset and communication failures, which are experimentally verified in the paper.

Is there a decentralized controller for an island microgrid?

A decentralized controller for an island microgrid is presented in Tucci et al. (2016). This controller has a general connection topology and uses the PLUG method which has offline control. To improve microgrid stability, there is a decentralized coordination control method in Cai et al. (2017) that uses V-I droop for PV cooperation in MGs.

What is a microgrid & how does it work?

It is a small village scale autonomous microgrid, composed of a 3-phase low-voltage network, solar PV generation, battery storage, and a backup generator. The grid is composed of overhead power lines and a communication cable running in parallel to serve monitoring and control requirements.

Can centralized hierarchical control be applied to a microgrid?

Nevertheless, simply applying the centralized hierarchical control strategies, traditionally used for utility electricity grids, onto the islanded microgrids would encounter several critical issues.

What are the technical challenges associated with microgrids?

Nevertheless, the technical challenges associated with the design, operation and control of Microgrids are immense. Equally important is the economic justification of Microgrids considering current electricity market environments and the quantified assessment of their benefits from the view of the various stakeholders involved.
