%T Real-Time Voltage Security Assessment (RTVSA) Tool Functional Specifications For Commercial Grade Application
%8 04/2007
%X <p>California Independent System Operator's (CA ISO) intends to implement a Real-Time Voltage Security Assessment (RTVSA) tool as a part of the suite of advanced computational tools for monitoring and preventing system problems and congestion management in the California ISO Control Area. Modern voltage assessment methods include such advanced functions as identification of real/reactive loading margins under different stressing conditions and associated weak elements, advice on selection of remedial actions and automatic development of operating nomograms and security regions. Real-time production-grade Voltage Security Assessment tools are becoming increasingly available nowadays. These tools are integrated with EMS/SCADA systems and use results from the state estimator.</p>
