摘要
动态等值是提高复杂大型互联系统动态行为分析速度的一种有效方法。在电力市场条件下,区域子系统运行具有相对独立性,系统数据具有一定的不透明性。本文研究了与市场条件相适应的区域互联电力系统发电机同调识别问题,基于经典的时域仿真算法,提出了一种子系统同调机群分布式识别方法。在支路分割的系统分裂下,邻接区域子系统间通过交换少量边界母线信息,完成区域迭代,实现对子系统同调机群识别。通过10机39节点系统算例,验证了该方法的有效性。
DynamiC equivalence is a valid approach to improve dynamical analysis speed of complicated power system. Under power market environment, the operation of subsystems is comparatively independent and the parameters of a subsystem are relatively nontransparent to another subsystem. In this paper, the dynamic equivalent problem for multi-area interconnected power systems is analyzed and a distributed algorithm for identifying coherent generators is presented based on the real-time simulation algorithm. Based on Branch Cutting and Subsystem Iterating, only a small amount of data between different subsystems needs to be exchanged in the developed algorithm. It is verified by IEEE lO-generator 39-bus system that the algorithm is valid and high performance.
