Abstract: Aiming at islanded DC microgrids, a cooperative control strategy based on consensus algorithm is proposed. In this strategy, the controllers for each distributed generation can achieve precise voltage control and power sharing, which only requires communication with neighboring units. However, the classic cooperative control schemes simultaneously require the knowledge of voltage and current information of their neighboring units, hence still have high communication burden. A unified distributed control strategy is proposed. This strategy integrates the voltage control and power sharing processes into one step, and eliminates the current information from neighboring units, greatly reducing the need of communication bandwidth. Finally, the effectiveness of the proposed method is verified by simulation.
