Contingency analysis (CA) is essential in maintaining a stable and secure power grid. It is required by operating standards that contingency violations need to be 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 user 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.
