In modern power grids, the fast and reliable detection of power-line outages is an important functionality, which prevents cascading failures and facilitates an accurate state estimation to monitor the real-time conditions of the grids. However, most of the existing approaches for outage detection suffer from two drawbacks, namely: (i) high computational complexity; and (ii) relying on a centra...

Data transport methods with end-to-end performance guarantees are required by the next generation distributed computing applications. Transport methods based on default best-effort IP networks are not capable of providing such guarantees due to complex traffic distributions in wide-area networks and highly dynamic network conditions. In this paper, we present a measurement-based transport metho...

Transmission congestions limit market activities and decrease possible benefits of energy market players. This paper introduces a portfolio of measures for a better use or increase of the transmission capacity of AC transmission lines. Novel approaches like stability monitoring, coordinated control and wide area protection are discussed. Their application to increase available transmission capa...

In this research, we propose an architectural solution to integrate the video voice over IP services in campus environment network and tested over LAN and WAN. Voice over IP technology has become a discussion issue for this time being. Today, the deployment of this technology on an organization truly can give a great financial benefit over traditional telephony. Therefore, this study is to anal...

The aim of this paper is to assess the capability of the emerging synchronized phasor measurement technology in improving the overall stability of the Hydro-Quebec’s transmission system through supplementary modulation of voltage regulators. Following a thorough singular value and eigenvalue analysis of the system dynamic interactions, five control sites consisting of four generators and one sy...

The electric power system is a cyber-physical system with power flow in the physical system and information flow in the cyber. Simulation is crucial to understanding the dynamics and control of electric power systems yet the underlying communication system has historically been ignored in these studies. This paper aims at meeting the increasing needs to simulate the operations of a real power s...

In this paper, the modeling for a complete scenario of a proposed wide area measurement system (WAMS) based on synchronized phasor measurement units (PMUs) technology with the access of a broadband communication capability is presented. The purpose is to increase the overall system efficiency and reliability for all power stages via significant dependence on WAMS as distributed intelligence age...

Controlled islanding is the last countermeasure for a bulk power system when it suffers from severe cascading contingencies. The objective of controlled islanding is to maintain the stability of each island and to keep the total loss of loads of the whole system to a minimum. This paper presents a novel integrated wide-area measurement systems (WAMS)-based adaptive controlled islanding strategy...

We present measurement approaches to evaluate performance optimizations, employed at different layers of the protocol stack, to enhance application performance over wide-area wireless networks (WWANs). Applications running over WWAN cellular environments (e.g web browsing) are significantly affected by the vagaries of the cellular wireless links. Much of the prior research has focussed on varie...
