摘　　要：提出了包括传统静态安全性和鞍结分岔稳定性的可用输电能力(Available Transfer Capability,ATC)的新模型.该模型将系统安全性约束的众多不等式转化为一个半光滑等式约束方程组,结合鞍结分岔稳定性的约束条件,构建了一类同时考虑安全性和稳定性的ATC模型的半光滑方程系统.基于光滑化策略和方法,建立了模型求解的Levenberg-Marquardt计算方法.9节点和30节点系统的计算结果表明该模型和计算方法的可行性和有效性.A new Available Transfer Capability （ATC） model considering conventional static security and saddle node bifurcation stability was presented. The model transforms many inequalities of security constraints into a system of semismooth equations. By integrating the saddle node bifurcation stability constraint, a ATC model with semismooth equations was constructed, which considered both security and stability. The Leven- berg-Marquardt algorithm to solve the ATC model was constructed by smoothing strategy and method. Numerical results of the 9-bus and 30-bus system have shown that the proposed model and algorithm are feasible and effective.
