Alleviating contingency violations through visual analytics and suggested actions

Contingency analysis (CA) is essential in maintaining a stable and secure power grid. Operating standards require that contingency violations are alleviated within 30 minutes. In today's practice, operators normally make decisions based on the information they have with limited support. This paper presents a new feature of suggested actions integrated in the graphical contingency analysis (GCA) tool, developed by the authors to help the operator's decision making process. This paper provides a few examples on showing how the decision support element of the GCA tool is further enhanced by this new feature to alleviate contingency violations for better grid reliability.
