| 摘 要： | 给出了一种求解暂态稳定约束下最优潮流(OTS)的快速方法。在该方法中,首先将势能边界面法与最小二乘法相结合,建立系统暂态稳定裕度与系统运行参数变化之间非线性关系的函数表达式;然后基于该函数表达式形成暂态稳定约束条件引入到常规最优潮流(OPF)模型中,从而形成OTS问题的数学模型。该文建立的OTS分析方法不仅使得OTS的求解规模与常规OPF相同,而且计算量亦与常规OPF基本一样。对新英格兰10机39节点典型系统的算例仿真表明了该OTS分析方法的有效性。

| Abstract: | The procedure of the new fast method is as follows.Firstly,by combining potential energy boundary surface(PEBS) method with least squares technique,the functional relation of transient energy margin with different generator power output and different clearing time is established.Then,the transient stability constraint based on the functional relation is formed and added into the traditional optimal power flow(OPF) mathematical model,and the OTS model is established.The OTS problem can be solved by traditional OPF optimization method with the same order of computation complexity.Simulation results on the 10-generator 39-bus New England test system are given to verify the effectiveness of the proposed method. |
