| 摘 要： | 为了将电力系统运行限定在静态稳定临界范围内,在最优潮流(OPF)模型中增加一组小扰动稳定指标作为不等式约束,建立了一种考虑小扰动稳定约束的最优潮流数学模型.以系统矩阵临界特征值的实部作为小扰动稳定指标,构造约束函数,并利用Cayley变换、谱函数理论及牛顿光滑化方法,对小扰动稳定约束进行转换,避免直接计算矩阵特征值,便于应用到大规模非线性系统.通过典型的WSCC 3机9节点系统,验证了所提方法的有效性.

| Abstract: | In order to limit power system operation in the critical range of static stable stability,a group of small-signal stability constraints as inequality constraints in the traditional optimal power flow model are added,and the optimal power flow mathematical model considering small-signal stability constraints is established in this paper.The critical eigenvalues real value of the system matrix as small-signal stability index is applied to form a constraint function,then the small-signal stability constraints ... |
