摘要：
In the voltage source converter based multi-terminal DC (VSC-MTDC) transmission system which considers the wind power prediction, a multi-objective optimal power flow (OPF) optimization algorithm is executed prior to the VSC-MTDC system to find the optimal reference values for the active power and DC voltages of the voltage-regulating converters. The control coefficient of each converter station is adjusted by referring to the generalized droop control to optimize the control strategy for the converter station in the VSC-MTDC system. At the same time, MATLAB is used to optimize the control strategy of the VSC-MTDC system considering the wind power prediction. By comparison with the results of the OPF algorithm in different cases for the VSC-MTDC system, the effectiveness of the proposed optimization method for control strategy is verified. © 2017 Automation of Electric Power Systems Press.
