Pipelined Numerical Integration on Reduced Accuracy Architectures for Power System Transient Simulations

Maher Kayal, Georgios Lilis, Sidi-Rachid Cherkaoui, Theodoros Kyriakidis, Guillaume Olivier Lanz

This work concerns a dedicated mixed-signal power system dynamic simulator. The equations that describe the behavior of a power system can be decoupled in a large linear system that is handled by the analog part of the hardware, and a set of differential e ...
