Real-Time Voltage Security Assessment (RTVSA) Algorithms Simulation & Validation Results

The Real-Time Voltage Security Assessment (RTVSA) project is designed to be part of the suite of advanced computational tools for congestion management that is slated for practical applications in California within the next couple of years. Modern voltage assessment methods include the development of such advanced functions as identification of weak elements, automatic selection of remedial actions and automatic development of composite operating nomograms and security regions. With all the research advancements in the area of Voltage Security Assessment over the past few decades, the feasibility of deploying production-grade VSA tools that run in real time and integrate with existing EMS/SCADA systems utilizing results from the state estimator, are increasingly becoming a reality.
