Measurement Campaign and Experimental Results of an Islanded Microgrid

Microgrids (MGs) represent surely the most challenging topic in electrical engineering, promising the decreasing of carbonization, the totally integration of different renewable sources and a cheap solution for those rural areas where electric distribution is economically unsustainable. The most important feature of a MG is represented by the possibility to work in islanded configuration in order to satisfy its own load without the support of the main grid. Literature is poor of experimental results on islanded MG and the research has focused on theoretical approaches on several topics, such as frequency, voltage stability, modeling, software simulations and energy management systems. The purpose of this article is to provide some experimental results such as power supply, voltage and frequency measurement during islanded operation. This test campaign was performed in the Smart Polygeneration Microgrid, a test tool of University of Genova created for experimental validation for grid-connected and islanded MG operation.
