本文提出了一种新的计算快速且准确的方法，用于评估可用传输能力（ATC），该方法基于所谓的三次样条插值技术的曲线拟合技术。该技术在ATC计算中的优点是能够减少耗时的交流潮流计算。三次样条插值技术描绘了电压幅值和功率流随有功功率传输的增加而变化的曲线。然后在电压或功率流限制与曲线相交的点确定 ATC。通过在实际测试系统上进行ATC评估，验证了该方法的有效性。从所提出的三次样条插值技术获得的 ATC 结果证明该方法具有令人满意的准确性，并且比使用递归交流潮流计算的 ATC 方法更快。
This paper presents a new computationally fast and accurate method for evaluating available transfer capability (ATC) based on a curve fitting technique so-called as the cubic-spline interpolation technique. The advantage of the technique in the computation of ATC is that it has the ability to reduce the time consuming AC power flow computations. The cubic-spline interpolation technique traces the curves of voltage magnitude and power flow variations with respect to the increase of real power transfer. ATC is then determined at the point where the voltage or power flow limits intersect the curves. The effectiveness of the proposed method is verified by illustrating the ATC evaluation on a practical test system. ATC results obtained from the proposed cubic-spline interpolation technique prove that the method is satisfactorily accurate and it is faster than the ATC method using the recursive AC power flow computations.
