Abstract

For a MGC system composed of multiple MGs, it is difficult to coordinate and unify control target information and data due to its large system size and numerous controllers. Considering the delay in communication between distributed power sources within a microgrid, a model of a microgrid cluster system with sparse communication networks is established, and a distributed containment secondary control strategy is proposed. By exchanging power information states with neighboring nodes, accurate power sharing can be achieved, improving the reliability and flexibility of the system. Finally, an experimental platform based on StarSim-HIL was built and experiments were conducted in various scenarios. The experimental results showed that under the proposed scheme, the microgrid group could achieve accurate power sharing and a high degree of autonomy in the microgrid region, verifying the effectiveness of the proposed strategy.
