15 صفحه اولOptimal 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...
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...
متن کاملArtificial Bee Colony based Optimal PMU Placement in Power System State Estimation
Advanced power system nowadays demands to ensure accurate estimate of the system states (bus voltages and angles) in order to ensure protection, monitoring, controlling and smooth running of the system. The conventional state estimator estimates the power system states based on the measurements obtained from the Supervisory Control and Data Acquisition (SCADA) system. Besides, the use of synchr...
متن کاملOptimal PMU placement for power system state estimation with random component outages
Phasor measurement unit s (PMUs) provide globally synchronized measurements of voltage and current phasors in real-time and at a high sampling rate. Hence, they permit improving the state estimation performance in power systems. In this paper we propose a novel method for optimal PMU placement in a power system suffering from random component outages (RCOs). In the proposed method, for a given ...
