Systematic small signal modeling and stability analysis of a microgrid

This paper presents a systematic, scalable, small-signal modelling approach for microgrids. Each subsystem is modelled separately and then all are interfaced using the Simulink Control-Design Toolbox. The main advantage is practicality, as analytical models of whole microgrids may be derived systematically and easily. The application to a subsystem-level (control design) and system-level analysis (microgrid stability) is shown, as well as experimental results that validate the correct operation of the microgrid.
