Market Modeling (Slides Only)

PowerWorld Corporation provides software training in the use of PowerWorld Simulator and add-on products OPF, SCOPF, OPF Reserves, ATC, PVQV, Transient Stability, and SimAuto. Our training also covers some basics of the engineering, operations, and economics of interconnected power systems.

Slides used in the 2-day course, Power System Economics and Market Modeling with PowerWorld Simulator, are available here. If you don’t yet have PowerWorld Simulator you can perform many of the exercises covered in these training modules on our free 13-bus evaluation version.
