A Framework for Phasor Measurement Placement in Hybrid State Estimation via Gauss-Newton
, 2013 In this paper, we study the placement of Phasor Measurement Units (PMU) for enhancing hybrid state estimation via the traditional Gauss-Newton method, which uses measurements from both PMU devices and Supervisory Control and Data Acquisition (SCADA ...

Redundancy based PMU placement in state estimation [PDF]
Sustainable Energy, Grids and Networks, 2015 Abstract An alternative method to obtain a PMU placement with maximum measurement redundancy is proposed in this paper. By considering the number of branches adjacent to each bus, the proposed method can be formulated in a linear and compact way. The effectiveness of the proposed method is shown by comparing its results with those of the existing ...

Optimal PMU Placement Using Nonlinear Programming
, 2014 Phasor Measurement Units (PMUs) are essential measuring devices for monitoring, control and protection of power systems. The objective of the optimal PMU placement (OPP) problem is to minimize the number of PMUs and select the bus locations to make a power system completely observable.

Optimal Multistage PMU Placement for Wide-Area Monitoring
IEEE Transactions on Power Systems, 2013 This paper proposes a novel optimization model to maximize the power system observability by placing phasor measurement units (PMUs) in a multistage manner. The problem is constrained by the financial budgets available at each installation stage. The budget may be spent on purchasing and installing new PMUs and relocating PMUs already installed in the ...
