PMU placement considering data uncertainty and redundancy
SoutheastCon 2015, 2015The increasing adoption of Phasor Measurement Units (PMUs, also known as synchrophasors) in the recent acceleration of smart grid technology has posed many interesting questions. One of the main problems that has been explored in many angles has been the PMU placement challenge: On which nodes of a system should the synchrophasors be installed to ...

Contingency-Constrained PMU Placement in Power Networks
IEEE Transactions on Power Systems, 2010In this paper, a model for the optimal placement of contingency-constrained phasor measurement units (PMUs) in electric power networks is presented. The conventional complete observability of power networks is first formulated and then, different contingency conditions in power networks including measurement losses and line outages are added to the ...

Optimal PMU placement for state estimation robustness
IEEE PES Innovative Smart Grid Technologies, Europe, 2014Given a sufficient number of properly placed synchronized voltage and current phasor measurements, an L1 estimator (also known as the Least Absolute Value or LAV estimator) can be shown to be robust against gross measurement errors. This paper is concerned about the placement of phasor measurement units (PMU) in order to establish a desired level of ...

PMU placement criteria for EPS state estimation
2008 Third International Conference on Electric Utility Deregulation and Restructuring and Power Technologies, 2008Phasor measurement units (PMUs) are employed in EPS both to solve the local problems and to obtain a general picture of EPS state which is further used for solution of control problems. Placement of PMU for solution of the problems of the first group is very specific and is determined by individual features of the problems to be solved.
