Abstract
This paper discusses the small-signal stability analysis of the combined droop and average power method for load sharing control of multiple distributed generation systems (DGS) in a stand-alone ac supply mode. The small-signal model is developed and its accuracy is verified from simulations of the original nonlinear model. It is shown that the small-signal model accurately predicts the stability of the parallel systems.
