Short-term probabilistic transmission congestion forecasting
2008 Third International Conference on Electric Utility Deregulation and Restructuring and Power Technologies, 2008This paper introduces a probabilistic method for short-term transmission congestion forecasting, which is recently developed by EPRI. The proposed method applies the sequential Monte Carlo simulation (MCS) in a probabilistic load flow as the conceptual framework, adds all the significant uncertainties and their probability distributions to be modeled ...

A zonal congestion management approach using ac transmission congestion distribution factors
Electric Power Systems Research, 2004In a deregulated electricity market, one of the major concerns of system operator (SO) is to ensure the free and fair electricity trading while maintaining system security and stability in meeting the pool and contract demands. Achieving a commercially transparent and technically feasible solution during transmission congestion, therefore, poses a ...

Valuing Transmission: Reliability, Congestion, and Uncertainty
SSRN Electronic Journal, 2008This paper investigates how the relationships between congestion, reliability, and uncertainty affect how electrical grid users value transmission system upgrades. The role that uncertainty plays in grid users' valuations of many of the congestion and reliability benefits of upgrades is emphasized.

Pareto optimality-based multi-objective transmission planning considering transmission congestion
Electric Power Systems Research, 2008In the deregulated environment, transmission congestion is one major problem that needs to be handled in power system operation and network expansion planning. This paper aims to enhance the transmission system capability and have the congestion alleviated using the multi-objective transmission expansion planning (MOTEP) approach.

Multistage transmission expansion planning alleviating the level of transmission congestion
2011 IEEE Trondheim PowerTech, 2011This paper presents a multistage transmission expansion planning (TEP) which alleviates the level of transmission congestion during the planning horizon. Due to the combinatorial nature of the proposed TEP model, a Benders decomposition approach intertwined with a manipulated disjunctive model is applied to decompose the original TEP problem into a ...

Transmission Congestion Management in restructured power systems
2011 International Conference on Emerging Trends in Electrical and Computer Technology, 2011Transmission congestion management is one of the critical and important tasks of the System Operator (SO). In this paper, congestion relief procedure has been discussed and compared with the objective of rescheduling cost minimization and proposed objective of real power loss minimization.

Congestion management in regional transmission organizations
2001 IEEE Porto Power Tech Proceedings (Cat. No.01EX502), 2002The implementation of Regional Transmission Organizations (RTOs), as encouraged in FERC Order 2000 in the United States, is requiring market based ancillary services including congestion management. This paper reviews the congestion management options being deployed in three Southeastern United States RTOs and provide details on one RTO congestion ...

Congestion Control Based on Transmission Times
2002Congestion leads to a severe performance degradation in multiprocessor interconnection networks. Therefore, the use of techniques that prevent network saturation are of crucial importance to avoid high execution times.In this paper, we propose a new mechanism that uses only local information to avoid network saturation in wormhole networks. In order to

Unit Commitment in Congested Transmission Systems
1999The presence of physical limitations on the amount of power that may be transferred through a given transmission line gives rise to a very vigorous debate on how to account for these limits in a deregulated utility environment. Many pricing schemes that account for line flow limits are being discussed and debated [10, 11, 23, 35], but no consensus has ...
