为便于分布式调度员培训仿真系统（DTS）中分布式潮流算法的应用，提出了一种计及频率变化的基于异步迭代的分布式动态潮流算法。该算法将互联系统采用协调层一子系统、发电机单元一网络单元2个不同层次的模型来表示。在上级调度中心建立协调层，由发电机单元实现频率变化时电网不平衡功率在各子系统发电机节点和负荷节点之间的分配，并进行频率仿真；在网络单元采用基于异步迭代模式的分布式算法进行全网的分布式潮流计算，通过网络单元与发电机单元之间的交替求解，求得全网频率变化仿真与潮流分布。以IEEE118节点扩展系统为例，对所提出算法进行验证，结果表明该算法能够准确地仿真分布式系统的频率变化并求解全网潮流分布。

For the application of distributed power flow algorithm in distributed DTS, a method called distributed dynami power flow algorithm based on asynchronous iteration mode considering frequency changes is proposed, Models of two differen levels are used to represent the interconnected system, including coordinate layer and subsystem model, generator unit aw network unit models. Coordinate layer is modeled in superior dispatching center. The generator unit is used to distribute th electromagnetic power in the network unit and simulate frequency of the system. In network unit, the power flows ar calculated with distributed algorithm based on asynchronous iteration mode. By iterative calculation between generator unit and network unit, the simulation of the frequency change and power flow solution can be obtained. The IEEE 118 node expande~ system is taken as an example to authenticate this method and the results indicate that the algorithm i~ neetlr~to
