Optimal PMU placement: A comprehensive literature review

2011 IEEE Power and Energy Society General Meeting, 2011
This review outlines the benefits that Phasor Measurement Unit (PMU) integration has on the power network. It reviews past optimal placement techniques covering meta-heuristic and deterministic algorithms. Three best performing algorithms are chosen in terms of minimum required number of PMUs for full system observability.
