Abstract

An adaptive backstepping based virtual inertial controller is encompassed to emulate the inertial characteristics of a synchronous machine in AC grid for a DC microgrid with various sources. This paper focuses on associating both AC and DC dynamics by estimating the angular momentum inertia and damping coefficient of the grid with the help of a voltage droop control used in the DC side. Moreover, a well-trodden power management strategy in the DC side under normal circumstances along with transition from inversion to rectification mode is proposed to increase the operational reliability. The robust performance of the proposed control strategy is tested under both simulated and experimental conditions.
