Abstract: A DC distribution network with multiple MMC converter stations requires coordinated operation among these stations to ensure the stability of the DC bus voltage and the power balance of the system. Based on the establishment of a complete mathematical model for the MMC converter station, this paper introduces multi-agent theory to construct a distributed coordinated control method. Relying on a sparse communication network established among converter stations, each converter station acts as an independent agent to achieve autonomous decision-making and cooperative control through information interaction, thereby realizing the preset power distribution targets among converter stations. On the AC grid side, the proposed coordination method adaptively provides proportional reactive power compensation based on the rated capacity and operating status of each converter station. To verify the effectiveness of the proposed method, a simulation platform is built to conduct verification tests. The results show that this method can accurately achieve the core objectives, including the stability of the DC bus voltage, the reasonable power distribution among converter stations, and the reactive power compensation on the AC side.
