| 摘 要： | 本文以牛顿拉夫逊法潮流计算为基础提出了一种新的随机潮流线性化系统.该系统充分利用了潮流计算结果,使随机潮流程序和计算大为简化.文中首次提出了随机静态稳定分析的概念,为研究电力系统运行方式、校验规划网络的可行性提供了简单而有效的工具.本文利用Gram-Charlier级数减少了随机潮流卷积的运算量.数字例表明,计算的精度是令人满意的,计算的速度明显超过了目前的算法。

| Abstract: | A probabilistic load flow model based on the Newton-Raph(?)on load flow approach is described in the paper.The now model not only allows the distri- butions of angles,voltages,active power flows and reactive power flows to be computed,but also gives the probability evaluation of losing static stability of the system.The method proposed is very simple and efficient.The numerical demonstrate that both accuracy and efficiency of the method are satisfactory examples for the practical purpo(?)e. |
