Abstract
GridPACKTM is a highly modular parallel computing package for developing power grid simulations that run on high-performance computing platforms. As one of the key modules in GridPACK, dynamic simulation assesses the transient behavior of power systems and plays an important role in determining the performance of dynamic security assessment applications which rely heavily on the computational speed and scalability of dynamic simulation. This paper presents an ongoing effort on redesigning the existing “fixed step” modified Euler explicit numerical integration scheme-based dynamic simulation module in GridPACK to incorporate numerically robust and efficient “variable step” implicit integration schemes. Promising computational performance over the explicit integration method in addition to the improved usability is presented in the paper as the outcome of this preliminary study.
