The topology of the microgrid. When designing a microgrid, developers usually regard economic metrics, and occasionally consider reliability and environmental aspects.
Among droop-controlled microgrids, the Kythnos Island microgrid is well known, which was built with the aim of developing centralized and decentralized control strategies for autonomous systems.
1. Introduction Microgrids offer a viable solution for integrating Distributed Energy Resources (DERs), including in particular variable and unpredictable renewable energy sources, low-voltage and medium-voltage into distribution networks.
Grid-connected microgrids are largely adopted to support the integration of DG units and, in particular, of renewable energy sources (RES) in distribution networks .
The PrInCE Lab microgrid project demonstrated that is possible to realize a microgrid by adopting components and equipment originally developed for classical distribution network applications. However, the adoption of these components made their integration into a microgrid structure more complex than the expected.
The metering system is constituted by remote I/O modules and meters capable to carry out from devices belonging to the Layer 0 all information required to monitor the operating state of the microgrid (i.e. voltage, frequency, power factor, active and reactive powers for each microgrid components and their status).
Several engineers and researchers along with institutions have proffered varied definitions for the term "microgrid." For example, the definition accepted by the International Electro-Technical Commission as proposed by Advance Grid Research at US Department of Energy for the microgrid is, "A microgrid is a group of interconnected loads and distributed …
