Abstract :
This paper proposes a new method for recognizing the price maker firms in the Independent System Operator (ISO)´s point of view. In the proposed methodology, at the first, all firms are supposed to be as price takers. Then the state of each firm will be changed from price taker to price maker and the obtained profit in either of cases is compared. In the proposed methodology the Supply Function Equilibrium (SFE) model is used for modeling a price maker firm´s bidding strategy. If a price maker firm changes the market clearing price (MCP) noticeably, that firm is realized as a price maker. GAMS (general algebraic modeling system) language has been used to solve the market simulation model using MINOS optimization software with non-linear programming.
