Mathematical Models for the Single-Channel and Multi-Channel PMU Allocation Problem and Their Solution Algorithms

Algorithms
Phasor measurement units (PMUs) are deployed at power grid nodes around the transmission grid, determining precise power system monitoring conditions. In real life, it is not realistic to place a PMU at every power grid node; thus, the lowest PMU number ...

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.
