| 摘 要： | 基于稳定域边界的主导不稳定平衡点（BCU）方法，求解暂态能量裕度对发电机有功和无功出力的解析灵敏度，再将暂态能量裕度约束直接加入最优潮流模型中，建立含多故障暂态能量裕度约束的最优潮流逐次线性规划模型。通过常规潮流计算、基于BCU法的暂态稳定及暂态能量裕度灵敏度计算、基于单纯形法的线性规划算法的交替求解，获得最优解。并对BCU方法和故障模式法进行了比较，在上述的交替求解过程中，故障模式法并不能保证能求出主导不稳定平衡点，但BCU方法能够给出可靠结果。新英格兰10机39节点系统的计算结果验证了所提方法的有效性。

| Abstract: | According to boundary of stability region based controlling u.e.p.method(BCU method),analytical sensitivitives between transient energy margin and active and reactive power of generators are solved,transient energy margin constraints are directly incorporated into optimal power flow model,and hence a successive linear programming model of optimal power flow problem with transient energy margin constraints under multi-contingency conditions is formulated.Through power flow calculation,BCU method based transi... |
