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 ...

Transmission Congestion Management

2003
The transmission network plays a key role in making the competitive electricity market work and the first important step in any power industry restructuring is open access to transmission. Transmission services have been unbundled from generation to form separate businesses, however, when regarded as a natural monopoly the transmission sector remains ...

Market power under transmission congestion constraints

PowerTech Budapest 99. Abstract Records. (Cat. No.99EX376), 2003
The main concern about market power in an electricity market is the concentration of ownership that would permit the exercise of market manipulation. The widespread potential for transmission congestion constraint is a crucial factor to improve the potential impacts of market power.

Transmission congestion and its social effects

IEEE Power Engineering Society General Meeting, 2005, 2005
Transmission networks play a major role in the open access deregulated power market. The condition where overloads in transmission lines occur is called congestion and transmission congestion is a major problem that needs more studies. Congestion segregates the power market, weakens the competition mechanism, and invalidates the optimization of the ...

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.

Aumann-Shapley transmission congestion pricing

IEEE Power Engineering Review, 2001
This paper describes a methodology for congestion cost allocation based on marginal costs and game-theoretic principles (Aumann-Shapley pricing). The methodology provides fair, economically efficient prices and ensures that the revenue collected from the transmission users will be equal to the cost of relieving the congestion.

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.

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.
