DCAT (Dynamic Contingency Analysis Tool)

Organization: Pacific Northwest National Laboratory
Year: 2018

In this day of mounting cyber attacks and natural disasters, the stability and resiliency of the electric grid has become of prime importance. Of high concern to many grid operators and local governments is the possibility of a cascading failure—a sequence of even minor events that results in an uncontrolled chain reaction. Currently grid analysis tools were built primarily to model steady-state operations and are challenged by today’s more dynamic power grid with its renewable energy sources and high-speed transmission. The Dynamic Contingency Analysis Tool (DCAT) bridges the gaps in cascading-outage analysis in a single, unique tool that automatically simulates and analyzes cascading sequences in real systems. It combines analysis of both traditional steady-state and newer dynamic operations in response to extreme events, DCAT screens for weak spots on the power grid, assesses the potential impact of cascading outages on power grid elements, and helps design proactive corrective actions more efficiently and effectively. DCAT can be used on laptops/desktops or in a highperformance computing environment. Under the latter, DCAT is up to 100 times faster than current analysis tools that cannot match its computing power or range of analysis.
