In this paper, a methodology for designing an optimal monitoring architecture by using a limited number of PMU (Phasor Measurement Units) and a PDC (Phase Data Concentrator) is proposed. The optimal design problem consists in defining the optimal location of both the PMU and the PDC by maximizing the expected value of the trace of the observability gramian of the power system over a large numbe...

The impact of Phasor Measurement Units (PMUs) for providing situational awareness to transmission system operators has been widely documented. Micro-PMUs (μPMUs) are an emerging sensing technology that can provide similar benefits to Distribution System Operators (DSOs), enabling a level of visibility into the distribution grid that was previously unattainable. In order to support the deploymen...

This paper presents a fault classification method for transmission lines based on voltage phasors using classification and regression trees (CART). The proposed method is intended to aid system operators in understanding the outputs of a PMU only state estimator. Faults are classified into four categories when the estimator is positive sequence and into ten categories when the estimator is thre...

In this paper, we present a testbed for smart grid communications over the Internet and investigate the influence of communication latency and the selection of protocols on the operation of the smart grid. The simulations are based on the open-source discrete event simulator OMNeT++ and the INET framework. Although the INET framework includes most protocols used on the Internet, the implementat...

Fast state estimation and system identification are essential to the reliability of the increasingly complex power system. Current estimation, on slower, steady-state, time scales does not model dynamics; however, with the deployment of phasor measurement units, faster estimation is now possible. We introduce a robust state estimator that learns the dynamic state of the power system on fast tim...

This paper aims to optimize the PMU (Phasor Measurement Unit) placement for a full observation of the power network and the minimum number of PMUs. In this paper, competition of Mixed Integer Non-Linear Programming and heuristically algorithms such as Bacterial Foraging Algorithm is presented. The results are demonstrated with PMU placement optimization simulation and a redundancy measurement a...

Secure and reliable opertation of the grid requires real time monitoring and control of entire power system. Phasor measurement units (PMU) are being deployed for real time monitoring and analysis of power system. The most important factor to be considered in placement problem is observability of power system with minimum number of PMUs. This paper proposed an Integer Linear Programming (ILP) b...

This paper presents a preliminary study of developing a novel distributed adaptive real-time learning framework for wide area monitoring of power systems integrated with distributed generations using synchrophasor technology. The framework comprises distributed agents (synchrophasors) for autonomous local condition monitoring and fault detection, and a central unit for generating global view fo...

The deployment of Phasor Measurement Units (PMUs) could support a new generation of wide area monitoring and situational awareness systems, but this has not yet occurred. Instead, PMU data exchange occurs through bi-lateral agreements, each reflecting substantial human involvement. Our work proposes a new model for PMU data sharing, based upon today’s cloud computing technology base. Cloud-base...

Widespread placement and high data sampling rate of current generation of Phasor Measurement Units (PMUs) in Wide Area Monitoring Systems (WAMS) result in huge amount of data to be analyzed and stored, making efficient storage of such data a priority. This paper presents a generalized compression technique that utilizes the inherent correlation within PMU data by exploiting both spatial and tem...
