摘要

在有关文献研究功角稳定控制负效应的基础上，分别发现切负荷对暂态频率及电压安全的控制负效应现象。利用扩展等面积准则及暂态频率和电压安全量化理论揭示其机理，探索电力系统稳定问题的复杂性，提高了切负荷控制优化的强壮性。给出一个简单的3机9节点算例可用于重现该现象，并通过大系统中的仿真实例说明问题的现实性。

Abstract

After uncovering the negative effects of angle stability control in 1997， negative effects of load shedding control on transient frequency and voltage security were discovered. Based on EEAC and the quantitative analysis theory of transient frequency and voltage security， the mechanism of the newly uncovered negative effects is deeply investigated. The complexity of power system stability is explored， and the robustness of optimal load shedding control is improved. A three-machine nine-bus case which is easy to reproduce is given， and also the cases of practical power systems are given.
