In the emerging deregulated electric power market, congestion management becomes extremely important and it can impose barrier to electric power trading. There are t w o types of congestion management methodologies to relieve congestion in transmission lines. One is non-cost free methods and another is cost-free methods, among them later method relieves the congestion technically whereas the fo...

Active queue management (AQM) is a group of FIFO based queue management mechanisms in a router to support end-to-end congestion control in the Internet. Until random early detection (RED) was proposed by the internet engineering task force (IETF) for deploying[1], FIFO based tail drop (TD) was the only AQM mechanism used in the network. Two main functions are used in AQM: one is the congestion ...

In recent years, the assessment of environmental performance has been received considerable attention by environmental policy indicators and decision makers. In this regard, this paper applies data envelopment analysis (DEA) as a management tool for evaluating the environmental performance of the firms and uses the extended bounded adjusted measure (extended BAM) for including undesirable outpu...

The Available Bit Rate (ABR) service class has been de ned by the ATM Forum. Closed-loop ratebased congestion control has been adopted by the ATM Forum as the standard approach for supporting ABR service in ATM networks. This paper examines congestion control mechanisms for ABR service and presents fundamental performance results for rate-based tra c management schemes under varying available b...

A model of congestion management is proposed in order to maintain adequate performance in both short term fluctuating traffic loads, and through long term predictable overloads. In this paper we present such a multi agent congestion framework by addressing three constituent facets: i) a formal queued network architecture for comprehending the fundamental effects of congestion, ii) a multi agent...

Abstract: The deregulated power system is quite popular in now a days. The increased power demand has forced the power system to operate very closer to its stability limits. So transmission congestion and voltage instability problems are arise in the power system. Due to the congestion in the network, not always possible to transmit the all contracted power. Congestion management is a tough tas...

With the continuous expanding of Internet scale, the network users and application increase rapidly and congestion control has become focus of network study. Several congestion control algorithms have been proposed out and improved for effective reduction of packet loss rate and for better utilization of network bandwidth. AQM (Active Queue Management) controls the queue length through intermed...

In this paper we propose a duality model of congestion control and apply it to TCP and active queue management schemes. Congestion control is the interaction of source rates with certain congestion measures in the network. The basic idea is to regard source rates as primal variables and congestion measures as dual variables, and congestion control as a Lagrangian method that iterates on source ...

The deregulation of power system has created an environment of competitiveness among different market players and the transmission lines are forced to operate near to their thermal or stability limits. It is a challenge with System Operators (SO) to ensure a secure and reliable transmission of power under these conditions. This paper proposes a rescheduling based congestion management strategy ...
