论文摘要
这封信提出了用于瞬态稳定性模拟的质量矩阵差分方程（DAE）公式。该公式具有两个突出的优势：与多种隐式DAE求解器兼容，并且可以根据传统公式（例如，通过将分母中的参数分为质量矩阵的对角线）来方便地实现。它还允许使用NULL时间常数降低动力学。关于使用Kundur的两个面积系统和2,000个公交系统的17个隐式求解器的时间和准确性进行了基准研究。
This letter proposes a mass-matrix differential-algebraic equation (DAE) formulation for transient stability simulation. This formulation has two prominent advantages: compatible with a multitude of implicit DAE solvers and can be conveniently implemented based on the traditional formulation, for example, by separating the parameters in denominators into the diagonals of the mass matrix. It also allows reducing the dynamics using null time constants. Benchmark studies are presented on the time and accuracy of 17 implicit solvers for the proposed formulation using the Kundur's two-area system and a 2,000 bus system.
