Impact of system state dynamics on PMU placement in the electric power grid
The goal of this paper is to study the impact of the dynamic nature of bus voltage magnitudes and phase angles, which constitute the state of the power system, on the phasor measurement unit (PMU) placement problem. To facilitate this study, the placement problem is addressed from the perspective of the electrical structure which, unlike existing work on PMU placement, accounts for the sensitiv...
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 کاملKalman Filters for Dynamic and Secure Smart Grid State Estimation
Combining dynamic state estimation methods such asKalmanfilterswith real-timedata generated/collected by digital meters such as phasor measurement units (PMU) can lead to advanced techniques for improving the quality of monitoring and controllability in smart grids. Classic Kalman filters achieve optimal performance with ideal systemmodels, which are usually hard to obtain in practice with unex...
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 ...
متن کاملState Estimation and Volt-Var Control in Smart Distribution Grid
Distribution smart grid is very important part of the smart grid. Utilities use Distribution Management System (DMS) as supervisory control layer at the power system control centers. State Estimation (SE) and Volt-Var Control (VVC) are the prime applications of the DMS. In the modern DMS, SE is required for extensive monitoring and control of the entire distribution network. In the presence of ...
