Increasing levels of complexity, due to growing volumes renewable generation with an associated influx power electronics, are placing increased demands on the reliable operation modern systems. Consequently, phasor measurement units (PMUs) being rapidly deployed in order further enhance situational awareness for system operators. This paper presents a novel data-driven event detection approach ...

The number and intensity of forest fires in the United States have been steadily increasing causing massive economic ecological damage. Overhead transmission distribution lines are typically disconnected preemptively near fires, a practice that causes high social cost. Deployment Phasor Measurement Units (PMUs) their ability for synchronized real-time measurement voltage current inspire here pr...

For power networks such as the Nordic Grid, that have operation constraints limits imposed by the existence of low-damped electromechanical oscillations, the estimation of electromechanical mode properties is of crucial importance for providing power system control room operators with adequate indicators of the stress of their network. This article addresses the practical application of differe...

Phasor measurement units (PMUs) are considered as a promising tool for future monitoring, protection and control of power systems. In this paper, a novel approach is proposed in order to determine the optimal number and locations of PMUs to make the power system observable. The PMU placement problem is formulated as a binary integer linear programming, in which the binary decision variables (0,...

Limited data feedback rate, e.g. 1-10 samples per second instead of 25-60, causes adverse effect on wide-area damping control (WADC). An observer driven system copy (OSC) approach is suggested here to deal with low data rates. The basic idea is to use the knowledge of nominal system dynamics to approximate the actual system behavior during intervals when data from phasor measurement units (PMUs...

Abstract—This paper presents a Generalized Binary Integer Linear Programming (GBILP) method for optimal allocation of Phasor Measurement Units (PMUs) and to generate Dynamic State Estimation (DSE) solution with complete observability. The GBILP method is formulated with Zero Injection Bus (ZIB) constraints to reduce the number of locations for placement of PMUs in the case of normal and single ...

Modern power grids are increasingly relying on real-time data, such as those from Phasor Measurement Units (PMUs), for their control and management operations. Due to its dependence on the Internet for data transfer, the grid is susceptible to a wide range of cyber attacks. Among these, data manipulation attacks are of particular interest in the context of PMU data, due to their potential for c...

In this paper, we present a Fingerprint Linear Estimation Routine (FLiER) to identify topology changes in power networks using readings from sparsely-deployed phasor measurement units (PMUs). When a power line, load, or generator trips in a network, or when a substation is reconfigured, the event leaves a unique “voltage fingerprint” of bus voltage changes that we can identify using only the po...

This paper presents a critical survey on different application of Phasor Measurement Units (PMUs) in electric power system networks incorporated with FACTS controllers for advanced power system operations, monitoring, control, and protection. Also this paper presents the current status of the research and developments in the field of the applications of PMUs in electric power system networks in...

Sensors like current transformers and voltage transformers are used to monitor the power systems and data from these sensors are collected in appropriate computer applications to observe the state of the power system. Phasor Measurement Units (PMUs) get data from current and voltage transformers and time-stamp them thereby paving the way for wide-area monitoring of the power system. In wide-are...
