NASPI^[1] process applied to locate Phasor Measurement Units (PMUs) within the New York Control Area (NYCA)

Abstract

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.

PMU placement for dynamic equivalencing of power systems under flow observability constraints

“…It will rather measure only m designated channel currents, m > 0 being the threshold number. Such constraints in flow observability has been reported for several PMUs operating in the Eastern Interconnect [11]. This type of constrained observability is also relevant when one or more analog channels of a PMU start malfunctioning, or are manipulated by extraneous malicious attacks, under which conditions the measurements from those channels cannot be relied on any more.…”

“…With increase in the number of PMUs in the US grid over the past decade, placement has also been dictated by several other driving purposes such as state estimation [9], and voltage monitoring near wind power sources [10]. An illustrative case study of this problem for the New York grid has recently been presented in [11]. An excellent taxonomy of various numerical optimization methods used for solving these PMU placement problems can be found in [12].…”
