Experimental Validation of a Dynamic Equivalent Model for Microgrids

The goal of this paper is the experimental validation a gray-box equivalent modeling approach applied to microgrids. main objective represent dynamic response microgrid with simplified model. contribution work two-step process, composed by definition nonlinear model operational constraints, adapted environment, and identification procedure used define parameters. Once parameters are identified, ready reproduce behavior voltage frequency variations, in terms active reactive power exchanges at point common coupling. To validate proposed approach, set tests have been carried out on real LV considering different configurations, including both grid-connected islanded operating conditions. Results show effectiveness technique applicability perform simulations.
