A new method for determination of static voltage collapse critical point based on Newton-Raphson load flow method with optimal multiplier is proposed in this paper. Different from continuation load flow and direct methods, this method starts from the infeasible region of load flow equations. It then approaches the desired critical point along the changing direction of injected power flow by making use of value of the optimal multiplier and the least square solution of load flow equations. All possible situations during the approaching process are analyzed and reactive power limits of generators are considered. The unified approach for identifying and calculating saddle node point and limit-induced bifurcation point is given. Convergence characteristic and computation complexity are analyzed. Tests in several systems show that the proposed method can converge at critical point after several iterations. The results are consistent with continuation load flow and direct methods.

给出了一种基于最优乘子潮流求静态电压稳定临界点的新方法。与连续潮流或直接法求解电压崩溃点不同,该方法从潮流的可行域外出发,利用潮流迭代过程中最优乘子的值和最小二乘解提供的信息,沿注入功率变化的方向逼近电压崩溃点。给出了判别和计算鞍结型和约束诱导型分岔点的方法,分析了逼近过程中的各种可能情况。对多个算例测试的结果表明:所提出的方法通过几次迭代即可收敛于静态电压稳定临界点,计算结果与应用连续潮流和直接法一致。
