“…In the second, a two stage SE is used, where the results of the first stage from a conventional SE and the phasor measurements are used in the second stage to form a linear SE. Inclusion of phasor measurements within static SE has been reported by several utilities [16][17][18][19]. The penetration of PMU measurements compared to conventional measurements is, however, still too limited to have a noticeable impact on the SE solution [20].…”

“…Frequency response analysis of power systems involves injecting a probing signal in one location and measuring the response at other locations [20][21][22][23]. In the US Western System, the probing signal can be either the pulse application of the 1,400 MW Chief Joseph braking resistor and the setpoint pulsing of the Celilo HVDC current injection.…”

The focus of this paper is the application of the NASPI [1] generated PMU placement process to locate thirty-nine (39) Phasor Measurement Units (PMUs) within the NYCA (NYCA Study). The material for this panel paper is based upon work supported by the Department of Energy under Award Number(s) DE-OE0000368 and is a collaborative effort between the New York ISO (NYISO) and the Transmission Owners (TOs) in the NYCA.The placement of PMUs discussed in the paper follows multiple criteria with the overall objective to locate PMUs to maximize system benefits, beyond those provided by conventional metering, and the existing energy management system (EMS) functions. The new capabilities enabled by the PMUs are Phasor enhanced visualization and situational awareness aided by various analytical functions.The functionalities for all of the 345/230 kV substations in NYCA are considered. A contribution of each substation to each of the functions of interest was assessed and a separate weight was assigned expressing how important a certain station is to each of the PMU functions. By tallying the cumulative weight of a station in support of all the functions, the station's rank was developed, which was then used to propose preferred substations for each of the TOs. Index Terms-Phasor Measurement Unit (PMU), Phasor Measurement Equipment (PME), NASPI, TransmissionPlanning.

“…This is due to two facts. First, angle reference determines the angle profile in the solved network and second, since phase angles are metered with respect to some other references that has no power system significance, if such measurements are added to the measurement set as is, each one of them will contain a bias that is equal to the angle shift between references [11]. Therefore the reference bus needs to be chosen among the PMU buses for each island, and all other phasor measurements values needs to be corrected using the following equation:…”

“…The purpose of these tests were, to evaluate the impact of phasor metering accuracy on the quality of the estimator solution, to show the relative effectiveness of phasor measurements with respect to RTU measurements, to identify the effect of the reference bus selection, to detect the impact of PMUs on the State Estimator convergence, and to establish the minimum clock synchronization sampling accuracy required for PMUs as it is indicated in [11]. A brief description of the pre-installation tests and their results are listed below.…”

This paper describes the implementation, testing, and performance of phasor measurements in an industrial state estimation at the New York Power Authority (NYPA). Phasor Measurement Units (PMU) with GPS synchronization were incorporated into the data acquisition subsystem of the Energy Management System (EMS). The modified State Estimator was subjected to pre-and post-field installation testing. The pre-field installation testing was done to verify the correctness of the solution algorithm, to identify the impact of phasor metering accuracy on the quality of estimator solution, to show the relative effectiveness of phasor measurements with respect to other measurements, to identify the effect of the reference bus selection, to detect the impact of PMUs on the State Estimator convergence, and to establish the minimum clock synchronization sampling accuracy required for the PMUs [10]. The post-field installation tests were conducted to identify the effectiveness of the PMUs in the State Estimator solution using the real-time data as well as to detect the effect of time skewing and measurement weights on the State Estimator solution. and since then has been involved in development and implementation of Advanced Application software. His area of interest is robust estimation, power system analysis and control, graph theory, and parallel processing.

Behruz (Bruce) Fardanesh received his B.S. in Electrical Engineering from Sharif University of Technology in Tehran, Iran in 1979. He also received his M.S. and Doctor of Engineering degrees both in Electrical Engineering from the University of Missouri-Rolla and Cleveland State University in 1981 and 1985, respectively. Since 1985 he has been teaching at Manhattan College where he holds the rank of Associate Professor of Electrical Engineering. Currently, he is also working in the area of Advanced Power Delivery in Research and Technology Development at the New York Power Authority. His areas of interest are power systems analysis, dynamics, control and operation.
