The Strategic Application of MMC Sequential Compensation Control in Energy Interaction of AC and DC Distribution Networks
With the deep integration and comprehensive development of the power system,the AC and DC distribution network has gradually become the core of optimizing energy consumption and ensuring grid stability.To study the impact of load imbalance on actual energy utilization in AC/DC distribution networks,a sequential compensation control strategy based on Modular Multilevel Con-verter(MMC)was proposed in this experiment to compensate for the splitting.The experiment first constructs the MMC topology structure and mathematical model of the AC/DC distribution network,and then integrates sequential compensation control to jointly control and improve the energy interaction of the AC/DC distribution network.The simulation results show that at time T1,MMC be-gan to implement reasonable compensation control for negative sequence and zero sequence currents,achieving effective adjustment.The final experiment shows that this strategy effectively controls unbalanced AC output and helps to improve the power quality of the AC/DC distribution network.
