Abstract:

To address the pollution problem caused by unbalanced nonlinear loads on the grid, this paper proposes a modular multilevel converter-based active power filter (MMC-APF) for optimal composite control of compensation currents based on multi-step model prediction. The compound control of PI and repetitive control (RC) is used to obtain the number of bridge arm pre-conductor sub-modules. On this basis, the multi-step model predictive control is used to narrow the search range for finding the optimal level of the objective function. There is no need to design the weighting factors, and the total number of sub-modules put into per phase bridge arm is [N-1, N+1], which can achieve 2N+1 maximum level number output, enhancing the MMC-APF AC side current tracking accuracy and improving the system dynamic performance. Meanwhile, a grouped hierarchical voltage equalization modulation strategy based on the predicted values of sub-module capacitance voltages is proposed, reduces the computational complexity of the equalization process, and lowers the switching frequency of sub-modules. Finally, the MMC-APF platform is built to verify the effectiveness of the proposed research scheme.
