On transmission congestion and pricing

IEEE Transactions on Power Systems, 1999
We provide a tutorial review, by example, of how to calculate optimal bus prices and congestion costs for a simple power system, using the "DC" loadflow approximation. It is also shown how to calculate the marginal effect of changing the impedance of a transmission on total system costs, and how this can be used for transmission planning purposes.

Transmission congestion management through optimal transmission switching

2011 IEEE Power and Energy Society General Meeting, 2011
In both restructured and vertically integrated power systems, it is desirable to transmit power to remote locations without causing any congestion and consequently avoiding inefficiency in generation dispatch. In this paper, in order to relieve network congestion, transmission switching is employed as a powerful tool to change network topology which ...

Congestion Control Based on Transmission Times

2002
Congestion 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

Congestion management and transmission rights

The Economics of Electricity Markets provides a cutting-edge analysis of the critical issues involved in the design and operation of electricity markets, as well as an assessment of alternative institutional arrangements that have either been implemented or are under discussion in Europe and the US.

Transmission congestion and expansion under regional transmission organizations

IEEE Power Engineering Review, 2002
A procedure to generate a list of benefits and optimal ca- pacity combinations for transmission path upgrades is suggested. Opti- mal upgrading of transmission can be identified from such a list. The benefits computed are a measure of congestion in the system.

Value of a Transmission Congestion Contract

SSRN Electronic Journal, 1998
This paper investigates the individual agent's incentive for setting Transmission Congestion Contract (TCC) magnitudes and its consequences in a POOLCO model of electric power market. TCCs do not completely solve the externality problem in an electric power market. Specifically, a TCC can have a negative value.

Flexibility in transmission switching for congestion management

2016 National Power Systems Conference (NPSC), 2016
In decentralized dispatch philosophy, system operator (SO) only deviate the final schedules in order to maintain network security (i.e. line overloading, outages, voltage and frequency deviations, etc.) in real time operation. Before going for the dispatch deviations, SO has the option of changing the network topology (i.e.

Congestion Management Using Optimal Transmission Switching

IEEE Systems Journal, 2018
In this paper, a multiobjective-based congestion management (CM) methodology is proposed using the optimal transmission switching (OTS) strategies considering the minimization of the total operating cost and the maximization of probabilistic reliability as two conflicting objectives.

Costs and benefits of transmission congestion management

2011 IEEE/PES Power Systems Conference and Exposition, 2011
Transmission congestion is a major economic and reliability concern in today's electric power systems. However, as the industry undergoes changes, it becomes critically important to better understand the fundamental role of transmission and its technical and financial effects on the electricity provision.

Estimating the actual cost of transmission system congestion

36th Annual Hawaii International Conference on System Sciences, 2003. Proceedings of the, 2003
This paper describes a methodology that could be used by a utility to estimate the actual cost of congestion on its transmission system using limited, non-state estimator data. The assumed problem inputs are a power flow model of an entire interconnected grid (i.e., the eastern interconnect), costs for the utility's generators, and then hourly values ...
