| 多馈入直流将对交直流混联系统的安全稳定运行产生重大影响。提出适用于交直流混联系统中直流输电间的系统和平均电压交互影响因子的定量计算方法；提出一种考虑直流输电间电压交互影响的交直流混联系统无功规划方法，上层规划以降低直流系统间电压交互影响为目标，下层规划以降低网损和无功投资成本最小为目标。IEEE 39 节点扩展系统的无功规划仿真和分析表明，所提方法对交直流混联系统的电压稳定性具有良好的改善作用。 |

| Abstract: |
| As multi-infeed HVDC greatly influences the safe and stable operation of hybrid AC/DC system, a method is proposed to quantitatively calculate the system voltage interaction factor and average voltage interaction factor between HVDC systems in hybrid AC/DC system. Furthermore, a reactive-power planning method considering the voltage interaction among HVDC systems is proposed, which takes the minimum voltage interaction as the objective of its upper layer while the minimum power-loss and minimum investment as the objectives of its lower layer. Simulation and analysis for IEEE 39-bus extended system show that the proposed reactive-power planning method improves the voltage stability of hybrid AC/DC system. |
