Observability-Enhanced PMU Placement Considering Conventional Measurements and Contingencies
Phasor Measurement Units (PMUs) are in growing attention in recent power systems because of their paramount abilities in state estimation. PMUs are placed in existing power systems where there are already installed conventional measurements, which can be helpful if they are considered in PMU optimal placement. In this paper, a method is proposed for optimal placement of PMUs incorporating conve...

متن کاملOptimal Multistage Scheduling of Pmu Placement for Power System Observability
The standards of power system monitoring, control and protection are elevated by Phasor Measurement Units (PMUs) as an auspicious tool. It is the purpose of this paper to determine the optimal number and locations of PMUs so as to make the system measurement model observable and also estimate the power system state. The proposed modelling approach which models PMU placement as an integer linear...

Saha Roy Power system state estimation with exclusive utilization of synchronous phasor measurements demands that the system should be completely observable through PMUs only. To have minimum number of PMUs, the PMU placement issue in an...
متن کاملOptimal PMU Placement in Power System Considering the Measurement Redundancy
In this paper, Integer Programming based methodology is presented for the optimal placement of Phasor Measurement Unit (PMU) that minimizes the cost of installation and provide the entire power system observability. The concepts of zero injection buses are used in this paper for further reduction in number of PMUs. Integer Programming may produce multiple results if neighboring buses to zero in...
