Research on the cooperative control strategy of output current in a distributed generation system

Abstract

In the ship degaussing system, a distributed power system is adopted, in which a single power module drives an independent coil load respectively. To ensure the degaussing effect, it is necessary to ensure the dynamic and static integrity of the load current. If an appropriate cooperative control strategy is not designed, the dynamic consistency of output current will be greatly affected by the difference in load. Therefore, this paper designs the cooperative control strategy based on the multi-agent consistency theory and proves the stability and consistency of the control strategy through the theory of discrete state space equation and graph theory. Through the simulation and experiment of multi distributed power system, it is verified that the control strategy has a good effect on improving the output current consistency of the power system.
