This paper aims to present an accurate and meaningful model of primary and secondary frequency control of low-inertia microgrids (MGs), composed of battery energy storage, wind and solar units. At the same time, the impact of Virtual Synchronous Generator (VSG) as well as PQ control method on frequency dynamic of the MG is discussed. Moreover, it is mathematically proven that the power sharing occurs based on the reverse proportion of the droop coefficients of diesel generator and the battery storage in the primary frequency control. But when the secondary control loop is applied, the battery storage just provides power in the transient time and produces no power in the steady state. Simulation results show that the frequency response of the MG improves once VSG control method is used for the inverters, as well as confirming the power sharing ratio, having been mathematically proven.
