This paper describes a virtual oscillator control (VOC) technique for single phase inverters operating in parallel. The suggested controller is based on the dynamics of the nonlinear Andronov-Hopf oscillator. Starting from the dynamic equation, the VOC controller is built, then the kinetics of the system are analyzed using the periodic average model. The average model is used, combined with a simple diagram of two inverters working in parallel to analyze the power-sharing strategy. This research focuses on power sharing, frequency and voltage synchronization between inverters working in parallel in the island Microgrid.
