Abstract :
Least Absolute Value (LAV) estimators that are based solely on phasor measurements are known to be robust against bad data provided that there is enough redundancy in the measurement set. This paper investigates the required level of redundancy and develops a systematic approach to place Phasor Measurement Units (PMU). The optimal placement will be such that it will guarantee robustness of the LAV state estimation while using a minimum number of PMUs.
