In a deregulated electricity market, CM is one of the key functions of a System Operator (SO) as congestion threatens system security and may cause rise in electricity price resulting in market inefficiency. Rescheduling generations and demands is an effective tool to relieve congestion. This paper presents a congestion management (CM) algorithm by optimal rescheduling of active powers of gener...

This paper deals with the following question associated with congestion pricing in a general network with either fixed or elastic travel demand: what is the maximum efficiency loss of a general second-best pricing scheme due to inexact marginal-cost pricing in comparison with the first-best pricing or system optimum case? A formal answer to this question is provided by establishing an inefficie...

Congestion is an important issue which researchers focus on in the Transmission Control Protocol (TCP) network environment. To keep the stability of the whole network, congestion control algorithms have been extensively studied. Queue management method employed by the routers is one of the important issues in the congestion control study. Active queue management (AQM) has been proposed as a rou...

This paper proposes a distributed optimization based dynamic tariff (DDT) method for congestion management in distribution networks with high penetration of electric vehicles (EVs) and heat pumps (HPs). The DDT method employs a decomposition based optimization method to have aggregators explicitly participate in congestion management, which gives more certainty and transparency compared to the ...

Since last few decades, electric supply industry is undergoing restructuring all over the world. Restructuring has brought organizational and operational changes by by the virtue of which Electricity has now become a commodity and regulated cost based electric power system is converted into price based liberalized power market. Under this competitive power market environment, number of market p...

Assessing and prioritizing the duration time and effects of traffic incidents on major roads present significant challenges for road network managers. This study examines the effect of numerous factors associated with various types of incidents on their duration and proposes an incident duration prediction model. Several parametric accelerated failure time hazard-based models were examined, inc...

We consider a multi-agent system where, at every time instant, many users choose to use one of multiple resources, whose performance depends on the number of concurrent users. In addition, a central agent has up-to-date knowledge of the congestion across all resources. What signals should the central agent broadcast to the individual users in order to reduce the total congestion? We model users...

Congestion in a network may occur when the load on the network is greater than the capacity of the network In this paper we analyzed active queue management algorithms with respect to their abilities of maintaining high resource utilization, identifying and restricting disproportionate bandwidth usage, and their deployment complexity. We compare the performance of RED, REM, and GREEN based on s...
