摘　　要：提出一种考虑系统静态电压稳定约束计算可用输电能力(Available Transfer Capability,ATC)的新方法。首先,构建考虑系统电压稳定约束(Voltage Stability Constraint,VSC)的最优潮流(Opti-mal Power Flow,OPF)模型,即基于VSC-OPF的ATC计算模型;然后,研究负荷增长因子变化对系统区域间ATC值的影响,并借助于内点法对优化模型进行求解,根据解轨迹上所取的系统运行点到电压崩溃点的距离,可求得不同电压稳定裕度所对应的ATC值;最后以IEEE-30节点3区系统的仿真分析验证了所建模型和方法的合理性和有效性。This paper proposes a novel and practical method for Available Transfer Capability（ATC） calculation in consideration of voltage stability constraint（VSC）.Firstly,ATC calculation model is constructed by enforce a voltage stability constraint（VSC） in an Optimal Power Flow（OPF） model.Then,With interior point method to solve VSC-OPF model,ATC values corresponding to different？system load growth factors can be calculated.According to distance from the operating point to voltage collapse point on the solution trajectory of the system,the ATC value corresponding to different voltage stability margin can be calculated.Finally,simulation and analysis on IEEE-30 bus 3-area system validate the efficiency and rationality of the proposed method.
