摘要/Abstract

摘要： 为保证分区电源对其分区内部换流站节点具有较强的电压控制能力，提出了一种交直流系统主导节点选择与无功分区的概率优化方法。通过对换流站进行负荷等值，模拟了源-荷-换流站节点功率的典型场景，进而采用机会约束计及源-荷-换流站节点功率变化时无功的分区平衡要求，建立考虑交直流耦合点可控性目标的优化模型，并基于目标相对占优的免疫遗传算法进行求解，从而进一步加强区域内电源对换流站的电压控制能力。基于IEEE 39节点系统进行仿真分析，仿真结果验证了所提方法的有效性。

Abstract: To ensure higher voltage control ability of regional power supply to the converter bus, a probabilistic optimization method for pilot-bus selection and network partitioning of AC/DC system is proposed in this paper. Through load equivalence of converter station, the typical node power scenarios of source-load-converter station are simulated. With consideration of the reactive power partitioning balance demand under the node power variation of source-load-converter station, an optimization model is established considering the controllability of the coupling bus of AC/DC system, and is solved by the immune genetic algorithm. As a result, the voltage control ability of the regional power to converter station is further improved. A simulation analysis is conducted on an IEEE 39 bus system, and the result verifies the effectiveness of the proposed method.
