Inverter parallelization for an islanded microgrid using the Hopf oscillator controller approach with self-synchronization capabilities

Nonlinear dynamical systems such as weakly coupled oscillators are an interesting approach to be adopted for the regulation of power inverters inside microgrids. Aiming at the synchronization and load sharing in islanded mirogrid, this paper is inspired by oscillator synchronization property to prop...
