Real Time Applications using Linear State Estimation Technology

This is a DOE Cost Share Project and 3 applications have been developed namely Real Time Contingency Analysis (RTCA), Voltage Stability Assessment Index (VSI), and Area Angle Limit Monitoring (AAM). Each of the applications uses Linear State Estimator Technology as an engine to derive results. RTCA is based on the linear state estimator which offers a guaranteed solution to provide a grid resiliency solution independent of EMS/SCADA and serve as backup to conventional RTCA. VSI provides a timely indication to operators when transmission capacity is decreasing and can be used to assess effects of remedial actions. AAM provides an important measure of transmission capacity that is not directly indicated by other techniques and can alert operators to a loss of capacity. The software has been installed and is undergoing testing at Bonneville Power Administration (BPA), and is planned for installation at New York Power Authority (NYPA) and Duke Energy.
