摘　　要：基于光滑化函数理论,建立了光滑化的可用传输容量(ATC)新模型。该模型将所有不等式约束的信息浓缩于一个等式中,从而避免了处理众多不等式约束而引起的非光滑性及由此产生的困难。采用牛顿法对光滑化的ATC模型进行求解,对IEEE 9节点、30节点及118节点标准测试系统进行了试算,并与传统的延拓潮流方法进行了比较。计算结果表明,所提出的模型和方法能快速可靠地识别出起作用的不等式约束,编程简单,是一种有效的ATC计算方法。A new smooth available transfer capability (ATC) model is constructed based on smooth function transformation. The model gathers information of all inequalities into one equation,- thus non-smooth problem caused by inequalities can be avoided. Newton method is adopted in this paper to solve the smooth ATC model. Numerical tests have been done on the standard IEEE 9-bus, 30-bus and 118-bus power systems and results are compared with a traditional continuation power flow method. Experiences show that the new smooth ATC model and the algorithm of this paper can identify the binding constraint reliably and quickly. The proposed model is easy for implementation and is applicable to real-world power systems.
