Contouring Method Considerations for Power Systems Applications

Contouring can be used to enhance engineers’ situational awareness during power system studies and events. This paper compares two contouring methods (Shepard and Delaunay-based) for power system applications. Power system case studies are presented to demonstrate and discuss contour choices in various steady-state and transient applications. Discussion is centralized around the following features: relative computation speed, realism, contour boundary, and smoothness.
