| چکیده | ||
| In deregulated electricity markets, strategic bidding plays an important role in a generation company’s (GENCO’s) profit maximization. A reasonable profit making bidding strategy is presented in this paper, taking into account price uncertainty as well as generator cost characteristics. Price uncertainty is considered through various statistical distributions, ensuring success in bidding process with a specified degree of confidence. The screening curve, generally used for economic evaluation of generating units in planning and operation studies, is utilized to characterize generator costs. The logically developed bidding strategy is implemented on a GENCO, that owns five different generating units. Fixed, variable and no load cost of generating units is taken into consideration to calculate GENCO profit. No load cost occurs when unit loses bid and cannot shutdown due to unit commitment constraints. Historical data of PJM electricity market is used to model price uncertainty. Finally, a comparative analysis is carried out to access the influence of accuracy of price uncertainty modeling on the GENCO profit. | ||
