【摘要】 提出了一种考虑暂态稳定约束的可用输电能力计算的新方法。采用约束转换技术处理系统动态方程中的微分方程,将函数空间的优化问题转换为Euclidean空间的优化问题,并利用非线性互补方法求解。该方法以原–对偶内点法为基础,通过引入一个特性函数来处理互补性条件,克服了原对偶内点法在每次迭代中都必须保持正方向的缺点,在效率上有很大的提高。该文以7节点系统和36节点系统的计算结果为例证实了该方法的有效性和合理性。更多还原

【Abstract】 An algorithm for available transfer capability (ATC) with transient stability constraints calculation is proposed, in which a optimization problem including differential equations in functional space can be transformed to an static optimization problem in Euclidean space via constraint transcription techniques. The transformed optimization model is soluted by a nonlinear complementarity method. This method is based on primal-dual interior method and employ a property function to handle the complementarity conditions, without requiring positive conditions be satisfied at every iteration. Numerical results illustrate the viability of the proposed model and method as applied to 7-bus and 36-bus systems.更多还原
