| 摘 要： | 在考虑风功率预测的多端柔性直流输电系统中,通过对交直流系统进行多目标潮流优化,将优化得到的各换流站有功功率和直流电压作为最优参考值,结合广义下垂控制对各换流站的控制系数进行调整,从而对多端柔性直流输电系统中各换流站的控制策略进行优化。同时,利用MATLAB对考虑风功率预测的多端柔性直流输电系统进行控制策略优化,对多种情况下的潮流结果进行分析比对,验证该控制策略优化方法的有效性。

| Abstract: | 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. |
