Abstract
This paper presents a small signal analysis for parallel connected inverters in stand-alone AC supply systems. The control technique of the inverters is based on frequency and voltage droop, which depends on the local variable measurements and do not need control interconnections. Simulation results show that the system is well represented by the small signal model, which makes stability studies easier. Preliminary experimental results are presented
