Fast Initial State Assessment for State Estimator using Optimally Located Phasor Measurement Units
Complex power systems need better observability and visualization capabilities to handle critical situations effectively. Synchro-phasor measurements provide intra second visibility to power system dynamics and enable faster control actions. A Phasor Measurement Unit (PMU) measures the voltage and current phasors (angle and magnitude) at a bus in a power system. In the literature, many methods ...
متن کاملPresenting a New Method Based on Branch Placement for Optimal Placement of Phasor Measurement Units
In this paper, a new method based on branch placement for the optimal positioning of Phasor Measurement Units (PMUs) in power systems is proposed. In this method, the PMUs are in type of single-channel and are installed at the beginning of the branches. Therefore, they are able to measure the bus voltages. Also, the installation of the PMUs on the branches increases the security of observabilit...
متن کاملRobust GPS-Based Timing for Phasor Measurement Units: A Position-Information- Aided Approach
The security and reliability of GPS receivers are critical to Phasor Measurement Units (PMUs). These devices provide synchronized voltage and current phasor measurements in power systems based on GPS timing. However, due to the unencrypted nature and low received signal to noise ratio of civil GPS signals, jamming and spoofing attacks on GPS receivers can pose a risk to both the position and ti...
متن کاملOptimal Placement of Phasor Measurement Units for Improving Power System State Estimation Accuracy: A Heuristic Approach
This paper describes a heuristic approach for optimal placement of phasor measurement units (PMUs) in power system for improving state estimation accuracy. PMUs are able to measure highly accurate bus voltage phasors as well as branch current phasors incident to the buses at which PMUs are installed. Due to cost consideration of PMU placement, power grid utilities are interested in the knowledg...
