Algorithms
In constrained nonlinear optimization, we aim to achieve two goals: one is to minimize the objective function, and the other is to satisfy the constraints. A common way to balance these competing targets is to use penalty functions.

Optimal placement of PMUs using differential evolution
2013 International Conference on Intelligent Systems and Signal Processing (ISSP), 2013In the present paper differential evolution methodology has been proposed to place minimum number of phasor measurement units (PMUs) at strategic locations of the power system such that the system is completely observable. Concept of integer programming formulation has been utilized for ensuring the observability of the system configuration and to ...

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 ...

Optimal PMU placement: A comprehensive literature review
2011 IEEE Power and Energy Society General Meeting, 2011This 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.
