Research and Simulation of Multi-Port Flexible DC Load Balancing Coordination Control Method

In order to solve the complex operating conditions and load imbalance existing in the operation and control of multi-port DC distribution networks, the networking operation mode suitable for multi-port DC distribution networks is discussed, and a hierarchical multi-port DC distribution network coordinated control architecture is proposed. Finally, a coordinated control strategy for multi-port flexible DC load balancing is proposed, and the effectiveness of the load balancing coordinated control strategy is verified through RTDS hardware-in-the-loop simulation. The research conducted has guiding significance for the implementation of stable control engineering of multi-port DC distribution networks.
