摘要

提出了一种考虑暂态稳定约束最优潮流的改进方法。将差分化后暂态过程中有限维约束转化为暂态过程末端时刻的一维不等式约束，较好地改善了考虑暂态稳定约束后优化规模庞大、计算负担重的状况，提高了同时考虑多个预想事故情况下的计算效率。在此基础上，探讨了暂态稳定计算的替代判据及其鲁棒性。在10机39节点系统上的测试结果证实了所提出的方法的意义。

Abstract

An improved method for transient stability-constrained optimal power flow is presented in this paper. The finite dimension transient constraints are transformed into one dimension inequality constraint in this method， so that it significantly reduces the computational burden and improves the calculation efficiency when multi-fault is resolved. A standard deviation criterion is proposed to measure the transient stability. The rationality of the substitute criterion and its robustness are analyzed. The proposed method has been validated in 10-machine， 39-bus test system.
