Modeling and Experimental Validation of an Islanded No-Inertia Microgrid Site

The paper proposes a simple but effective model for no-inertia microgrids suitable to represent the instantaneous values of its meaningful electric variables, becoming a useful platform to test innovative control logics and energy management systems. The proposed model is validated against a more detailed microgrid representation implemented in the electromagnetic simulator PSCAD-EMTDC and then against experimental data collected on the University of Genoa test bed facility. Recorded data highlight a good tradeoff in matching the results of the proposed model, confirming its suitability to be used for the preliminary testing of new control logics for islanded microgrids.
