Optimal Micro-PMU Placement Using Mutual Information Theory in Distribution Networks
Energies, 2018 Micro-phasor measurement unit (μPMU) is under fast development and becoming more and more important for application in future distribution networks. It is unrealistic and unaffordable to place all buses with μPMUs because of the high costs, leading

Optimal PMU placement for modeling power grid observability with mathematical programming methods
International Transactions on Electrical Energy Systems, 2020 Phasor measurement units (PMUs) can obtain synchronized voltage and current phasors to increase the accuracy of state estimation results. Optimal PMU placement (OPP) reduces the required number of PMUs to make the system fully observable.
