Participants behaviors in Iran electricity market forecasting and evaluation

The offering strategies of Gencoes could change SCUC (Security Constraint Unit Commitment) convergence. As a result, the profit of generating plants will be adjusted. In this paper the minimum profit alteration with no changes in power production is named, as "discrete strategy". Different discrete strategies based on marginal cost is tested and compared with other strategies. Revenue is modeled with game theory to find Nash equilibrium as mixed game; therefore, market power indices are estimated. This model will help ISO to simulate violations before the occurrence of market. Due to the existence of uncertainty in producer's strategy, model is implemented in probabilistic pivotal technique. The model, finally, is evaluated on IEEE 30 buses test case system market power indices are calculated. The results of this method indicate the impact of players on the performance of Iran electricity market and highlight the strategies which may lead to market power abuse.
