Interactive Tutorial

This tutorial features a fictitious power system the size of a medium-sized city. The simulations explore several facets of power system planning and operations, including: addition or removal of transmission facilities addition, de-rating, or removal of generating resources demand response and use of customer-owned generation, such as rooftop solar physical or cyber attack on a […]

Registering SimAuto

SimAuto must be registered in the Windows Registry before it can be referenced from external programming platforms. This normally happens automatically when Simulator is installed, but may need to be performed again if there is a hardware change or if you are working with multiple versions of Simulator. (Only one version of SimAuto may be […]
