Abstract

High penetration of distributed interface converters (DICs) in the isolated AC micro-grid (MG) may result in poor frequency and voltage response due to low inertia of conventional DICs. In order to overcome this difficulty, the concept of the virtual synchronous generators was proposed recently. meanwhile, in order to improve the convergence rate of the conventional consensus-based droop control and resilience to noises, new implementation of consensus-based distributed droop control by Alternating Direction Multipliers Methods (AD-MMs) is proposed. Possible extensions of the proposed method to two variants, including consensus ADMM with double message exchange and unique message exchange, are also discussed. Numerical experiments of a 14-bus/6-DIC micro-grid system on real-time digital simulators are performed to validate the effectiveness of the proposed distributed droop control mechanism.
