Large number of contracted power exchanges among sellers and purchasers, in a deregulated market causes transmission line congestion. Congestion lines undermines the security economy networks. Flexible AC system (FACTS) devices are introduced at appropriate spots to change flow order keep within their capability. In this work, most commonly used unified controller (UPFC) is proposed for achieve...

This paper deals with the, AC power flow approximation has been used to calculate new real Power Transmission Congestion Distribution Factors (PTCDFs), considering the presence of an UPFC. These factors have been utilized to form the single and multiple zones for the congestion management. The UPFC has been optimally placed in the system based on the factors, called as Line Loading Distribution...

Open access electric network faces severe congestions due to the increasing demand for power, multiple transactions in the transmission line and outage of network equipment, causing uncertainty and affecting the system security. In this article, different operating states are considered for congestion management in an electric power network. An effective algorithm to reschedule the generating u...

We design an efficient on-line approach, FlowMate, for partitioning flows at a busy server into flow groups that share bottlenecks. These groups are periodically input to congestion coordination, aggregation, load balancing, admission control, or pricing modules. FlowMate uses inband packet delay measurements to the receivers to determine shared bottlenecks among flows. Packet delay information...

Congestion indicates an economic state where inputs are overly invested. Evidence of congestion occurs whenever reducing some inputs can increase outputs. In this paper, we present a new model to identify and evaluate congestion in Data Envelopment Analysis (DEA). We use output efficient DMUs to construct our proposed model to evaluate congestion. We also proposed a linear inequality and equali...

ADAPTIVE routing algorithm has been employed in multichip interconnection networks in order to improve network performance. Does a algorithm use local or global network state? This is the key question in adaptive routing. In many traffic patterns, the ignorance of global network state, leading to routing selection based only on local congestion information, tends to violate global load balance....

Modal shift in public transport as a consequence of disruption on line has some cases unforeseen consequences such an increase congestion the rest network. How information is provided to users and their behavior plays central role configurations. We introduce here simple stylised agent-based model aimed at understanding impact behavioural parameters modal shift. The applied case study based sta...

This research assesses how U.S. transit agencies have taken advantage of congestion pricing projects and answers two questions: (1) what role has transit played in U.S. congestion pricing projects, and (2) how have transit agencies responded to congestion pricing projects through service planning, operating practices, capital investment, and institutional arrangements. First, transit is seen as...

The role of Independent System Operator (ISO) in the restructured power industry includes system control, capacity planning, transmission tariff and congestion management; the challenging task being minimizing the congestion. One of the popular techniques used to alleviate congestion is using Flexible AC Transmission Systems (FACTS) devices. The power system generally operates near its rated ca...

This paper presents a framework to carry out an novel method based Optimal Power Flow (OPF) for transmission congestion management in deregulated power system using Thyristor Controlled Series Capacitor (TCSC) and Generation Rescheduling. In the deregulated environment, some generators may not be willing to participate in the congestion management process for their own economic interest or some...
