This paper reports the results of a series of oral double auction experiments in which some traders possess market power. A market is set up in which the configuration of supply and demand curves leads to an asymmetry between buyers and sellers in their abilities to influence transactions prices. This market structure does not always lead to convergence to the competitive price despite the comp...

In this paper, a new reactive power market clearing (RPMC) mechanism for day-ahead competitive electricity market is developed based on multi-objective optimization approach. In proposed mechanism, three objective functions such as total payment function (TPF) for reactive power support from generators and synchronous condensers, total real transmission loss (TRTL) and voltage stability enhance...

A Payment Cost Minimization auction has been proposed as an alternative to the Offer Cost Minimization auction for use in wholesale electric power markets with an intention to lower procurement cost of electricity. Efficiency concerns have been raised for this proposal while assuming that the true production costs would be revealed to the auctioneer in a competitive market. Using an experimenta...

This paper presents one comprehensive modelling approach for maintenance scheduling problem of thermal power units in competitive market. This problem is formulated as a 0/1 mixedinteger linear programming model. Model incorporates long-term bilateral contracts with defined profiles of power and price, and weekly forecasted market prices for market auction. The effectiveness of the proposed mod...

Transmission congestion is the major challenge in the operation of competitive power market. Sufficient transmission corridor is necessary for realization of power transaction. This paper proposes an efficient approach for transmission congestion management using the Black Hole Algorithm (BHA). Congestion is relieved by rescheduling of real power from the market clearing schedule. BHA is a rece...

the goal of this paper is to compile strategies for a chinese international telecommunication vendor which entered into iran telecom market in the year 2000. since zte is involved with business in more than 135 countries and it is out of our power to collect huge data from all over the world, we have limited our strategies to iranian market and we will compile strategies for iran business unit...

With the increased use of sensitive electronic circuitry, customers become more concerned about the electric power quality (PQ). In the new open-access and competitive power market, electricity consumers are in a unique position to demand a higher quality of service. The utilities or other power providers have to ensure a high quality of their service to remain competitive and retain/attract th...
