Abstract Considering the intrinsic limitations of reactive power range of shunt side for the unified power flow controllers based on indirect matrix converters (IMC-UPFC),a model predictive control (MPC) strategy is proposed to enlarge the reactive power range of the shunt side in this paper. The prediction model of line current for series side and the reactive power of shunt side for IMC-UPFC were deduced, and a comprehensive cost function was formed to control the power flow in the transmission line and extend the reactive power range of shunt side. Then, the optimal switching state of IMC with minimum cost function was synthesized to achieve the control objectives. MPC control strategy has the advantages of simple algorithm and no additional modulation rules. And the Matlab/Simulink simulation results for IMC-UPFC in two-bus network show that the proposed MPC control strategy can effectively enlarges the reactive power range of IMC-UPFC in shunt side, and further proves the rationality and correctness of the scheme.

Key words： Indirect matrix converters (IMC) unified power flow controllers (UPFC) model predictive control (MPC) extending the reactive power range of shunt side
