Designing A Microgrid To Improve Continuity Of Service And Flexibility The Case Of Politecnico Di Milano Leonardo Campus

The widespread of Distributed Generation calls for moreadvanced solutions in the management of local electricgrids. In this sense, Microgrids allow increasing reliabilityof supply and quality of service in local distribution ofelectricity. Moreover, a proper management of privategrids helps increasing hosting capacity of DistributionNetworks, reducing costs sustained by end users forelectricity consumption, and keeping the electric systembalanced through the exploitation of local dispatchingresources. In this paper the Microgrid implemented in theCampus of Politecnico di Milano is described. TheMicrogrid of Campus Leonardo hosts a CombinedCooling, Heating and Power plant (2 MW el ) and twobackup generators (1.6 MW el ), plus some smaller PVplants. The advanced load management solution is basedon Schweitzer Engineering Laboratories (SEL)components. It provides new capacity for facing networkrequirements in case of emergency and allows maintaininga high level of quality of service. Moreover, it enables theparticipation of the Campus to the Italian AncillaryServices Market as a virtual unit.
