  This paper proposes a new distributed consensus-based control method for
voltage and frequency control of fully inverter-based islanded microgrids
(MGs). The proposed method includes the active power sharing in voltage control
to improve the reactive power sharing accuracy and thus generalizes some
existing secondary frequency and voltage control methods. Firstly, frequency is
regulated by distributed secondary frequency control. Secondly, voltage is
regulated by distributed average voltage control and decentralized individual
voltage control. It offers a tunable trade-off between voltage regulation,
active, and reactive power sharing accuracy. Therefore, it avoids the abuse of
sacrificing reactive power sharing accuracy for exact voltage regulation which
is a common issue of existing methods. The proposed method is implemented in a
distributed way that does not require a prior knowledge of the MG network
structure and loads and hence can ensure scalability. Simulation results shows
that the proposed controller achieves different compromise between the above
three targets under different modes of operation.
