Consensus-Based Distributed Control for Reactive Power Sharing in Autonomous Microgrid under Communication Noises

Distributed control relies on communication network among distributed generators (DGs), which is commonly influenced by noises. Furthermore, reactive power deviations may be deteriorated under different communication noises. In this paper, an improved consensus-based distributed control considering communication noises is developed in AC autonomous microgrids, which is capable of attenuating the impact of noises. The traditional consensus-based distributed control is introduced and noises are also considered in traditional control. In order to attenuate the influence of noises, a consensus gain function is involved, which can attenuate the impacts in reactive power sharing. By using this proposed method, the proportional reactive power sharing is achieved under noises. Simulation results verify the effectiveness of the proposed method.
