Acknowledgements The Power Systems Engineering Research Center sponsored the research project titled “Enhanced State Estimators.” The project began 2004 and is expected to be completed in 2005. This report is an intermediate report of progress at Arizona State University. We express our appreciation for the support provided by PSERC’s industrial members and by the National Science Foundation under grant NSF EEC-0001880 received under the Industry / University Cooperative Research Center program. The authors thank all PSERC members for their technical advice on the project, especially Dale Krummen (AEP), Jay Giri (AREVA T&D), Jerome Ryckbosch (RTE), and Ram Adapa (EPRI) who are industry advisors for the project. The authors also acknowledge Drs. Ali Abur and A. P. Sakis Meliopoulos of Texas A&M University and Georgia Tech respectively who contributed technical advice and data to this work. Dr. Abur is the project leader. i

Executive Summary This report deals with the placement of phasor measurement units (PMUs) based on the improvement in error in the estimate of the voltage phase angles in power systems. The present technology measures voltage, current, and real and reactive power for determining the operating condition of the electric network. This technology cannot measure voltage phase angle directly. Thus, voltage phase angles must be found by state estimation.
