Optimal PMU placement using Iterated Local Search
International Journal of Electrical Power & Energy Systems, 2010 An essential tool for power system monitoring is state estimation. Using PMUs can greatly improve the state estimation process. However, for state estimation, the PMUs should be placed appropriately in the network. The problem of optimal PMU placement for full observability is analysed in this paper.

Optimal Placement of Phasor Measurement Unit in Smart Grids Considering Multiple Constraints
Journal of Modern Power Systems and Clean Energy, 2023 The distribution of measurement noise is usually assumed to be Gaussian in the optimal phasor measurement unit (PMU) placement (OPP) problem. However, this is not always accurate in practice.

Groebner bases algorithm for optimal PMU placement
International Journal of Electrical Power & Energy Systems, 2020 Abstract In this paper a new method for solving optimal phasor measurement units (PMU) placement problem for full observability in power systems is proposed. A new algorithm is based on forming and solving Groebner bases set of equations for a defined optimization problem.
