Abstract

Abstract:

In order to solve the problem of insufficient freedom of power flow control in flexible DC power grid and improve dynamic performance,a model predictive control strategy for multi-port interline power flow controller (MI-PFC) is proposed.Firstly,the mathematical modeling of the multi-port DC network containing MI-PFC is discretized.Secondly,the cost function and weight factor are designed and the control is accomplished by sub-module ranking algorithm and modulation strategy.Finally,the control performance of the proposed model predictive control strategy is verified by MATLAB/Simulink simulation platform.The final proof shows that the proposed control strategy has advantages such as strong dynamic performance,multi-objective control,and simple structure.

Key words: DC power flow controller, model predictive control, modular multilevel converter, control strategy, dynamic performance
