摘要
提出了一种考虑暂态稳定约束的可用输电能力(ATC)的计算方法。建立了在传统的静态ATC模型中加入暂态稳定约束的有效方法,并在此基础上给出了动态ATC问题的优化计算模型。同时提出了求解动态ATC问题的内点非线性规划算法。该算法不仅具有强大的处理等式约束和不等式约束的能力,而且具有良好的收敛性,能够有效求解动态ATC问题。所提出的模型与算法已在若干系统得到了验证,文中以IEEJ-WEST10和IEEJ-WEST30系统的计算结果为例说明了该方法的有效性。
This paper studies the development of evaluating dynamic available transfer capability (ATC) with transient stability constraints being considered. By establishing a novel method for integrating transient stability constraints into conventional steady-state ATC, the dynamic ATC problem is successfully formulated as an optimization problem. The paper also proposes a solution of dynamic ATC based on interior point nonlinear programming algorithm. The proposed solution algorithm not only has strong ability to deal with equality constraints and inequality constraints, but also provides good convergence characteristic. The method has been implemented and tested in several systems. Results of IEEJ-WEST10 and IEEJ-WEST30 are studied in this paper to illustrate the effectiveness of the proposed approach.
