摘要

对直流输电系统2种常用的运行模式进行分析，讨论了多馈入直流输电（MIDC）系统输送功率对受端交流系统网损的影响，提出了2种条件下网损灵敏度的计算方法，一种是保持MIDC系统输送通道总功率不变，另一种是MIDC系统各直流线路输送功率相互独立。第2种情况下，需要采用负荷平衡方法进行修正。针对第1种情况，文中对功率的再分配进行了讨论，提出了一种有效的功率再分配方法来降低受端系统网络损耗。对加入了MIDC系统的IEEE 118节点系统进行仿真的结果表明，优化后三馈入DC/AC的118节点交流系统网损平均降低0.97%。

Abstract

By analyzing two operational modes of DC systems， the influence of the power of multi-infeed direct current（MIDC） systems on the loss of the inverter-side AC system is discussed in this paper. A method is presented to calculate the loss sensitivity at the two operational modes. One operation mode is that the total active power of MIDC systems is kept constant， and the other is that the active power of each line in MIDC systems is independent of each other. The sensitivity needs to be modified with load equilibrium factor in the latter case. At the first case， an effective algorithm for adjusting the active power of MIDC systems to reduce the loss of inverter-side AC system is presented. Numerical tests in IEEE 118-bus system show that the proposed algorithm is effective and the average reduced loss of 118-bus system with 3-infeed DC system is 0.97%.
