      this paper proposes a new method that uses the combination of particle swarm optimization (pso) and simulated annealing (sa) to predict the bidding strategy of generating companies (gencos) in an electricity market where they have incomplete information about their opponents and market mechanism of payment is pay as bid. in the proposed methodology, gencos prepare their strategic bids according to supply function equilibrium (sfe) model and they change their bidding strategies until nash equilibrium points are obtained. nash equilibrium points constitute a central solution concept in game theory and they are computed with solving a global optimization problem. in this paper a new computational intelligence technique is introduced that can be used to solve the nash optimization problem. this new procedure, is based on the pso algorithm, which uses sa method to avoid becoming trapped in local minima or maxima and improve the velocity’s function of particles. the performance of this procedure is compared with results of other computational intelligence techniques such as pso, genetic algorithm (ga), and a mathematical method (gams/dicopt). the ieee 39-bus test system is employed to illustrate and verify the results of the proposed method.
