Abstract :
This paper presents a small-signal model suitable to analyze the stability and dynamic characteristics of multiple inverter-based distributed generation (DG) systems and the associated positive feedback anti-islanding scheme. The developed model is validated by comparing its results against those obtained by detailed, non-linear electromagnetic transient simulations. With the developed model, the sensitivity analysis can be conducted to study the small-signal stability of the multiple inverter-based DG systems.
