摘 要：The information technology (IT) world has changed fundamentally and drastically from running software applications on a single computer with a single CPU to now running software as services in distributed and parallel computing environment. Power system operation has been also shifted from being solely based on off-line planning study to more and more real-time market-driven. Facing these challenges, we will discuss in this chapter how to design power system analysis and simulation software to take advantage of the new IT technologies and to meet the real-time application requirements, using the InterPSS project as a concrete example.
