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.
