Virtual Oscillator Control for inverters based on reduced-order Andronov-Hopf oscillator

Abstract This paper proposes a virtual oscillator control method by reducing the order of amplitude term Andronov-Hopf dynamic process. The proposed retains its steady-state droop characteristic and power dispatchability in grid-connected mode, but with less nonlinearity. At same time, based on performance criterion inverter, detailed parameter selection principle controller is given, verified simulation. Finally, we compared full-order oscillation controller. results show that has stronger load capacity.
