A simplified first harmonic model for the Savona Campus Smart Polygeneration Microgrid

Microgrids (MGs) may represent a new answer to many old problems in energy and electric world, such as pollution, high reliability, efficiency and so on. The MG rapid increase implies a fast transformation of the electric power systems that are now characterized by new energy sources requiring dedicated control architectures and simulation tools. Unfortunately, the majority of such new sources are connected to the MG by means of power electronic converters that often make it impossible to replicate some of the concepts, tools and control philosophies commonly used in traditional networks. For this reason, there is a strong need of developing models for MG structures that can be reliable but sufficiently simple to be used for the control system design. In this framework, this paper presents a simplified first harmonic model for the Smart Polygeneration Microgrid (SPM) located in the Savona Campus of the University of Genoa that allows the interface with many controllers. The developed simplified model is validated comparing it with a complete simulation performed in the PSCAD-EMTDC environment that allows to represent each component with a high level of detail
