A Plug-and-Play, Scalable Control Method for AC Island Microgrid

In this paper, a scalable, plug-and-play (PnP) and system-stable synthesis control method is proposed for the AC island microgrid consisting of a distributed generator units (DGUs) and loads connected by power lines. The proposed method only requires a limited global parameter design controller, so the design process of the controller is decentralized, so that the

Power Sharing in Island Microgrids

The main idea behind microgrids is to have the electrical grid divided into sub-grids, each of them with power and management systems (also known as nanogrids Burmester et al. (2017)). The microgrid should be able to operate in grid-connected or in island mode Hatziargyriou (2013), where the latter requires having an Energy Storage System (ESS).

Island & Microgrids

Microgrids are similar, but also have the capability to connect synchronously to a large network. Island grids are typically the result of geographical circumstances that render the connection to a large network costly or even impossible. Microgrids, in contrast, are designed to increase the security of supply in case the large network breaks down.
