摘　　要：灵活高效地制定现代电力系统的合理运行方式遇到了越来越大的挑战。为提高电力部门制定运行方式的效率和灵活性,本文提出一种电压驱动的潮流样本生成方法,通过发电机输出功率转移分布因子将断面有功潮流约束转化为发电机有功注入功率的调整,基于直流潮流将发电机有功注入转化为节点电压相角的指定。该方法能充分考虑各种节点约束,电压初值相量经过合理调整后能够准确得到满足断面有功约束的潮流样本。该方法不需要进行迭代求解,计算速度快且成功率高。It is a great challenge to formulate a reasonable operation mode flexibly and efficiently for complex modern power systems.In this paper,to improve the efficiency and flexibility when formulating the operation mode for power utilities,a voltage-driven power flow sample generation method is proposed,which can convert the transmission section active power flow constraints into the adjustment of generator active power injection through the generation shift distribu⁃tion factor,and then convert the generator active power injection into the designation of node voltage phase angle based on the DC power flow.After the initial voltage phasor is reasonably adjusted with the consideration of different node con⁃straints,the power flow samples satisfying the transmission section active power constraint can be obtained.This meth⁃od does not need any iterative solution,and it also has a high calculation speed and a high success rate.
