This article proposes a novel synchrophasor-based control scheme enabling controlled islanding, islanded operation and automatic re-synchronization of distributed energy resource (DER) in distribution network. The performance the proposed system is studied using test power model. DER controller uses centralized architecture, receiving phasor measurement unit (PMU) measurements from both transmi...

<span>Sustained growth in the demand with unprecedented investments transmission infrastructure resulted narrow operational margins for power system operators across globe. As a result, networks are operating near to stability limits. This has demanded electrical utilities explore new avenues control and protection of wide area systems. Present supervisory data acquisition/energy manageme...

This paper presents a method for designing minimal measurement set that include both Supervisory Control And Data Acquisition (SCADA) and Synchronized Phasor Measurements Units (SPMU) data for a Hybrid State Estimation (HSE). The optimal location of Phasor Measurement Units (PMU) is performed by Binary Integer Linear Programming (BILP). Among these PMUs, the highest priority indexed PMUs are se...

In this paper, frequency oscillation has been present as it is an important issue in power systems, especially when joined to the new trend use alternative energies energy source, well be a big risk for inter-connection of modern electric networks. Wind farm acts and connected two buses on Iraqi system. Because low-frequency monitoring needs accurate fast, main objective propose novel online sy...

Online transmission line outage detection over the entire network enables timely corrective action to be taken, which prevents a local event from cascading into large scale blackout. Line aims detect an as soon possible after it happened. Traditional methods either do not consider transient dynamics following or require full Phasor Measurement Unit (PMU) deployment. Using voltage phase angle da...

Egypt is moving towards smart grid infrastructures to enable efficient bidirectional power supply with reduced carbon footprint. The target smart grid will feature distributed energy generation with renewable energy systems. With the improvement of wind power technology in Egypt, increase of wind power capacity, the impact of wind power on the grid has become an important research topic as well...

Phasor measurement units (PMUs) are important devices for protection, monitoring, and control of modern power systems. Unlike the supervisory data acquisition (SCADA) system which only measure magnitude, PMUs can provide a set synchronized phasor measurements with high sampling rate accuracy less than one second, better monitoring especially during outages. Since costly devices, operator is not...

Abstract Large-scale power grid observability is still a challenge because of deteriorating infrastructure and the incorporation renewable energy sources. A smart that makes use cutting-edge technology, such as phasor measurement unit (PMU), an excellent option for monitoring bringing networks up to speed with latest information. Latterly, considerable investment required deployment locations h...

Saha Roy Power system state estimation with exclusive utilization of synchronous phasor measurements demands that the system should be completely observable through PMUs only. To have minimum number of PMUs, the PMU placement issue in an...

Community microgrids are set to change the landscape of future energy markets. The technology is being deployed in many cities around globe. However, a wide-scale deployment faces three major issues: initial synchronization with utility grids, slip management during its operation, and mitigation distortions produced by inverter. This paper proposes Phasor Measurement Unit (PMU) Assisted Inverte...
