─ In the absence of synchronous generator, distributed energy resources such as solar or wind generations need to provide inertia support to guarantee stable operation of a low-inertia islanded AC microgrid. This paper proposes a distributed method to regulate the system frequency by emulating the behavior of a conventional synchronous generator in term of virtual inertia control, using the coordination of both reserved active and reactive power of distributed energy resources. This paper proposed a multi-layer hierarchical control structure for MGs, using consensus algorithm and Andronov-Hopf based Virtual Oscillator Control. The proposed method, besides providing advantages of conventional AHO over well-known droop control method, is able to eliminate the frequency deviation and improves the system frequency response, while maintaining accurate load power-sharing among DERs in proportion to their …
