Abstract :
In this paper we study frequency stabilisation in inverter-based microgrid systems with primary droop controller and decentralised secondary control strategy. For the microgrid with any configuration of inverter buses, we establish conditions for trajectory ultimate boundedness and derive an explicit description of an estimate of the region of attraction to the ultimate bound set.
