| 摘 要： | 针对互联电网区域间限制联络线传输功率的要求,提出了一种系统扰动后维持联络线功率为设定值的新算法。该算法设定联络线的交换功率,分区域潮流计算,可以实现通过改变受端系统侧的运行方式,维持联络线功率为设定值的目的。该算法物理意义清晰,容易实现,收敛性好,给出的算例验证了提出算法的可行性。

| Abstract: | This paper presents a new power flow algorithm based on tie-line power equivalence constraints after disturbance considering the necessary inter-area power constraints' need.The normal load flow is used in sending-area and multi-swing bus load flow is implemented on receiving-area.The method proposed aims to keep specified tie-line flow constraints unchangeable through changing the mode of operation on receiving-area.The algorithm has an obvious physical meaning and a good convergence characteristic.The results of modified IEEE14 test system show the effectiveness of the proposed algorithm. |
